#8149: GHC should warn about redundant import of a type name also if one of its record selectors is imported ------------------------------------+------------------------------------- Reporter: Lemming | Owner: Type: bug | 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: | ------------------------------------+------------------------------------- Sorry, I have another corner case for a redundant import warning: {{{ module Main where import Control.Monad.Trans.Writer (WriterT, runWriterT) main :: IO () main = undefined runWriterT }}} This module will not provoke a warning, although the import of WriterT can be omitted. I assume this is because runWriterT is a record selector of WriterT and could (or should?) be imported as: {{{ import Control.Monad.Trans.Writer (WriterT(runWriterT)) }}} Since I used runWriterT like a regular function I did not care about its record selector feature. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8149> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #8094: Intermittent segfault when using ghc-7.6.3 -e on OSX 10.6.8

Running commands with `ghc -e` sometimes produces a segfault. {{{ % ghc -e 'return ()' ; echo $? 0 % ghc -e 'return ()' ; echo $? zsh: segmentation fault ghc -e 'return ()' 139 }}} I don't know exactly what's causing it, but I'm suspicious of the binary distributed with the package. When I pull it up in `gdb`, there are warnings pertaining to missing object files expected to be in a `/Users/ian` directory. There's never been an `ian` user on my machine, so I suspect that's an artifact from whomever built the binary. This may also be the root of the intermittent segfault {{{ % cd /Library/Frameworks/GHC.framework/Versions/7.6.3-x86_64/usr/lib/ghc-7.6.3 % gdb ghc GNU gdb 6.3.50-20050815 (Apple version gdb-1518) (Sat Feb 12 02:52:12 UTC 2011) Copyright 2004 Free Software Foundation, Inc.

It can be accepted in any position of an identifier except the first, where Haskell requires the character to be either upper/title-case (conid) or lower (varid). isLetter x && not (isUpper x) does not imply isLower(x). -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8068> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

This slows down builds, especially cabal ones.
