Comment (by simonmar):
Can someone check whether {{{-fno-unit-at-a-time}}} makes a difference?
That is, add {{{-optc-fno-unit-at-a-time}}} to the offending compilation.
x86_64 has been using this flag for a while, I'm not sure why we haven't
needed it on x86 too - or maybe we just didn't notice. I don't have gcc
4.x on our x86 boxes here.

Re: [GHC] #738: ghc can't load files with selinux Enforcing
Jens Petersen wrote: Perhaps someone who knows SELinux would like to describe how to set up an exception for GHC so we can put it in the FAQ? I have added: /usr/bin/chcon -t unconfined_execmem_exec_t /path/to/binary/prog to the %post install scripts of the darcs and haddock packages in Fedora Extras for now, and will do the same for the ghc package (it needs it for more programs). This avoids having to set allow_execmem system wide. I just wonder if the ghc case is harder since programs compiled by ghc using the rts need exceptions too not just ghc itself. Of course if the RTS was a shared library on Linux, then probably just its .so file would need to have execmem context set. I have added this information to the FAQ, thanks.

Comment:
Excellent bug report; Core Lint wins again.
It turns out that there's a long-standing bug, which I have now fixed.
tc204 tests.
(I fear the commit message may say tc203, but it's 204!)
Meanwhile, I think should be able to work around by replacing
{{{
...?y...?y...?y...
{{{
let x = ?y in ...x...x..x..
}}}

[GHC] #811: GHC panics when compiling some mutually recursive modules that export something imported

This happened in my own code, and then I reduced it to a much simpler
test-case. I wished to try it in another compiler, if only to make doubly
sure that it is correct code, but I couldn't get any to work with (these)
mutually recursive modules (for a variety of reasons). So, unless I am
quite mistaken, I am unable to compile my Haskell-98 program at this
point.
Following are the four files to cause the error, then the command to
invoke GHC (6.4.2, but 6.4.1 also failed for me in the same way) and the
result.
!CausesRecursiveModules.hs:
{{{
--This module is what makes MainBug need a .hs-boot file.
module CausesRecursiveModules () where
import {-# SOURCE #-} MainBug ()
}}}
!ExportsSomething.hs:
{{{
-- This module by itself triggers no bug, but is necessary
-- as something for MainBug to externally import.
-- Something triggers the bug at least whether it's a thing,
-- a type-alias, or a data definition (with the appropriate
-- capitalization for each). (I tested those, as can be seen
-- in the commented code below.)
module ExportsSomething (Something) where
type Something = ()
--data Something = MkSomething
--something :: (); something = undefined
}}}
!MainBug.hs:
{{{
--The export of Something here is necessary to trigger the bug,
-- as well as it being externally imported.
--(Actually the bug still happens if Something is not exported
-- here and module ExportsSomething is not imported here at all,
-- but that violates the expectation that the .hs-boot file
-- should be a subset of the main .hs file.)
--Importing CausesRecursiveModules here is necessary
-- to cause recursive modules.
--Rather than import ExportsSomething, it also triggers the bug to re-
export
-- something from the Prelude, such as 'id'; as it is, though, the bug
-- still happens with -fno-implicit-prelude.
module MainBug (Something) where
import ExportsSomething (Something)
import CausesRecursiveModules ()
}}}
!MainBug.hs-boot:
{{{
--The export of Something here is necessary to trigger the bug,
-- as well as it being externally imported.
--Note that Something is not actually and does not need to actually
-- be imported by anyone from module MainBug (although the bug still
happens
-- if it is; it's just not the simplest test-case then!)
--Rather than import ExportsSomething, it also triggers the bug to re-
export
-- something from the Prelude, such as 'id'; as it is, though, the bug
-- still happens with -fno-implicit-prelude.
module MainBug (Something) where
import ExportsSomething (Something)
}}}
I've uploaded those four files at
http://isaac.cedarswampstudios.org/2006/GHC6.4.2RecursiveModulesBug.tar.gz
for convenience.
This is the exact command and result to reproduce the bug, although
variations on command-line arguments as well as trying to compile
!CausesRecursiveModules.hs instead all seem to produce about the same
error. I didn't try figuring out how to do it without --make, though.
{{{
$ ghc --make MainBug.hs
Chasing modules from: MainBug.hs
Compiling ExportsSomething ( ./ExportsSomething.hs, ./ExportsSomething.o )
