I didn't change `testsuite/tests/rename/should_fail/Makefile`! 2. `Makefile`s like having tabs in them. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/10033> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #9855: Harbormaster uses the wrong code sometimes

#9855: Harbormaster uses the wrong code sometimes -------------------------------------+------------------------------------- Reporter: goldfire | Owner: hvr Type: bug | Status: new Priority: normal | Milestone: Component: Trac & Git | Version: Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Harbormaster sometimes uses an inconsistent codebase for building, and then reports spurious build errors. A specific example is [https://phabricator.haskell.org/harbormaster/build/2444/ here]. The line where the error is reported is correct in the Differential view, but somehow Harbormaster is confused. Even stranger, this particular error could result only if ''part'' of a file were out-of-date. Something somewhere is trying to be awfully clever and failing. I know that sometimes I have deviated from any recommended Phab workflow. I attest that, to the best of my knowledge, I have not done so with this patch. It is based off my `origin/master`, and I have done no rebasing since posting on Phab. I have not pushed to the central GHC repo, but that doesn't appear to be necessary. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9855> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

This should be fixed. Even better, scrap many of the very old versions, as they're unsupported, anyway.

There seem to be at least three problems * Some unexpected failures. Let's ignore those for now, since they are probably all different * Some Python traceback stuff; this must be a bug. * Tons of warnings about `haddock-interfaces` Could someone help with these. Yes, I can just ignore all this output, but it seems wrong.

#10044: Wrong line number reported with CPP and line beginning with # -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: low | Milestone: Component: Compiler | Version: 7.10.1-rc2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Blocked By: Test Case: | Related Tickets: Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- If I compile {{{ {-# LANGUAGE CPP #-} module Bug where {- # hi there! -} * }}} I'm told of a parse error for the `*` on line 10. But that `*` is line 9! The problem is that, with `CPP` on, the line number counter gets confused if a line begins with a #, perhaps after whitespace. I actually hit this and was confused in real code. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/10044> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #9235: Simplifier ticks exhausted on recursive class method

#9235: Simplifier ticks exhausted on recursive class method -----------------------------------+--------------------------------------- Reporter: klao | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Compile-time crash Unknown/Multiple | Test Case: Difficulty: Unknown | Blocking: Blocked By: | Related Tickets: | -----------------------------------+--------------------------------------- GHC 7.8 and HEAD panic on the following code: {{{#!haskell module C where class C a where c :: C a => a -> Int c a = c a {-# INLINE c #-} instance C () x :: Int x = c () }}} Note that it's the coincidence of the 3 conditions that triggers this bug: 1. the `c` method has to be inlined (explicity or implicitly) 2. it has to be recursive (but, it doesn't have to be as dumbly recursive as in the example) 3. it has to have this weird, slightly mistaken type signature: `C a => a -> Int` instead of simply `a -> Int`. But, when this incidentally happens (in my case, both 2. ''and'' 3. were unintentional), the user gets a very hard to debug issue. They don't even get an indication which module is responsible if `c` is used from a different module than the one with the class definition. Also note that this happens even with a non-optimized build. And in this example `c` has to be explicitly marked NOINLINE to prevent it. (In the instance that I caught in the wild simply removing the INLINE annotation was enough.) Finally, on a side note: shouldn't 3. by itself be an error? Or a warning at least? -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9235> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
