Bugzilla Bug 212305

While testing ghc-6.8.2 with gcc 3.4 I ran into the following problem:

------------------------------------------------------------------------
== make all -r;
 in /var/tmp/portage/dev-lang/ghc-6.8.2/work/ghc-6.8.2/rts
------------------------------------------------------------------------
../compiler/ghc-inplace -optc-O -optc-O2 -optc-pipe -optc-Wa,--noexecstack
-optc-Wall -optc-W -optc-Wstrict-prototypes -optc-Wmissing-prototypes
-optc-Wmissing-declarations -optc-Winline -optc-Waggregate-return

-optc-fno-strict-aliasing -H16m -O -opta-Wa,--noexecstack -w -optc-O2
-package-name rts -optc-DNOSMP -static -I../gmp/gmpbuild -I. -#include
HCIncludes.h -dcmm-lint     -c Adjustor.c -o Adjustor.o


And that's it. It sits there for at least 4 hours. The process does not use any
cpu. I'm lost what this could cause...

ghc strace from 6.6.1

I started a build again (now with gcc-4.3.1 and ghc-6.6.1, because this is a
version you can do a bootstrap build with) and the build halts at the same
moment.

this is the strace coming from ghc.

Build also stops here on autoAdjuster with gcc 4.1:

Same happens with gcc 4.3.1

Same with 6.6 too :(

I have a different failure:

Version 6.6.1 has the same problem, as related in bug 202212. The same
workaround also works with this version.

"LC_ALL=C emerge ghc" makes it work...

when I attempt to build I see the following :

Looks like someone is more or less passing crap to the assembler.

going to try setting LC_ALL=C .. which is odd since that shoudl be the default
locale.

It's a problem of ghc-6.4.2 binary (and source) build. It dislikes big-endian
64 bit platforms. I just pushed patches for ghc-6.4.2-r1 and ghc-6.6.1-r1 BE64
fixes and rebuilt them successfully (ghc-6.4.2 requires older gcc):
http://code.haskell.org/~slyfox/ghc-ppc64/unregisterised-nodoc/
However, those are not exact binary builds we use in gentoo: there is not
documentation.

The one build I've done properly is ghc-6.10.4 in overlay:
http://code.haskell.org/gentoo/gentoo-haskell/dev-lang/ghc/ghc-6.10.4.ebuild .
Testing is greatly appreciated.
Thanks!
