#9306: Crash when shifting Integers too much ------------------------------------+------------------------------------- Reporter: dfeuer | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 7.8.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: Runtime crash Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- When shifting an Integer by `fromIntegral (maxBound::Int) + 2` or more, the RTS crashes. The attached program gives the following output (on x86_64, at least): [dfeuer@lemur src]$ ./shiftcrash Okay 0 gmp: overflow in mpz type Aborted I found the bug in 7.6.3, but it's been verified to be present also in 7.8.3.

#8347: Add a Strict LANGUAGE pragma ------------------------------------+------------------------------------- Reporter: tibbe | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- A `Strict` `LANGUAGE` pragma would allow us to experiment with writing in a strict sub-language. Since this pragma works on a per module basis, it needs to be modular. I propose the following semantics: * Patterns are strict at the top-level, as if they had a top-level bang, unless an explicit ~ is used to make the pattern lazy. * Functions evaluate their parameters to WHNF. * Data type fields are strict (as if they had a bang-pattern). -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8347> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#8424: quasi-quotes have carriage returns on Windows ------------------------------------+------------------------------------- Reporter: GregWeber | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Template Haskell | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- A Windows user rerported using Data.Text.IO.writeFile to write out quasi- quoted text. writeFile automatically translates '\r' to "\r\n", so the user ended up writing out "\r\r\n" to a file. Haskell seems to be adopting the policy or removing '\r' from Haskell land. Is there any reason why quasi-quotes should not automatically strip carriage returns? I asked this question on ghc-users and there was no response. I am willing to make this fix if it is deemed appropriate. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8424> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #9348: "Symbol not found" when using a shared library

#9348: "Symbol not found" when using a shared library -----------------------------------+----------------------------------- Reporter: alex.davis | Owner: simonmar Type: bug | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 7.8.3 Keywords: | Differential Revisions: Operating System: MacOS X | Architecture: x86 Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -----------------------------------+----------------------------------- I'm trying to make a shared library from a simple program. It works fine on my Windows box, but gives an error on Mac OS X. Furthermore, the error seems to be generated from one of GHC's shared libraries. What happens is this. I compile my shared library with GHC, which works fine. But when I try to use it from another program (specifically, R), I get an error message containing the following: Symbol not found: _stg_IND_STATIC_info Referenced from: /usr/local/lib/ghc-7.8.3/ghc-prim-0.3.1.0/libHSghc- prim-0.3.1.0-ghc7.8.3.dylib Expected in: flat namespace in /usr/local/lib/ghc-7.8.3/ghc-prim-0.3.1.0/libHSghc- prim-0.3.1.0-ghc7.8.3.dylib More details: The program I'm trying to use is R. In R, you load a shared library with the command "dyn.load". When I try this, the command I use is "dyn.load('final.dylib')", and the full error message is what follows: --- Error in dyn.load("final.dylib") : unable to load shared object '/Users/alexanderdavis/Desktop/illustrate bug copy/final.dylib': dlopen(/Users/alexanderdavis/Desktop/illustrate bug copy/final.dylib, 6): Symbol not found: _stg_IND_STATIC_info Referenced from: /usr/local/lib/ghc-7.8.3/ghc-prim-0.3.1.0/libHSghc- prim-0.3.1.0-ghc7.8.3.dylib Expected in: flat namespace in /usr/local/lib/ghc-7.8.3/ghc-prim-0.3.1.0/libHSghc- prim-0.3.1.0-ghc7.8.3.dylib --- As I said, I have done all of this with no trouble on Windows. I compiled into a DLL, loaded the program into R, and was able to use the functions in it. My Mac OS version is 10.9.4. My R version is 3.0.2. When loaded, it displays "Platform: x86_64-apple- darwin10.8.0 (64-bit)", but Sys.getev("R_ARCH") returns the empty string. Command used for compiler: ghc --make -dynamic -fPIC -shared SumRoots.hs StartEnd.c -o final.dylib The code is attached. It is from a blog post by Neil Mitchelll (author of HLint) about calling Haskell from R: http://neilmitchell.blogspot.com/2011/10/calling-haskell-from-r.html -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9348> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#9378: Make unknown LANGUAGE pragmas a warning, not an error -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Currently, if I say `{-# LANGUAGE Foo #-}` at the top of my file, it fails to compile. This failure seems unnecessary, especially because any new language feature `Foo` enables will fail to compile later on down the file. Is it possible to have a "stern warning" that is produced even when other parts of the file produce errors? The reason I'm bringing this up is that, when 7.8 came out with its role annotations, users needed CPP in two different places: both to protect the `RoleAnnotations` pragma and to protect the role annotations themselves. This may be unavoidable on the role annotations directly, but I think we can improve the situation around `LANGUAGE` pragmas. Is there a downside to this? -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9378> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
