Bug 135651 – dev-lang/ghc-6.4.2 compiles incorrectly

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description marty rosenberg 2006-06-05 10:07:00 UTC]

ghc compiled without a problem, but now, none of it's components seem to work correctly.  All of the components seem to have the same problem. . .running out of memory.  
USE="X -qt -kde sse sse2 dvd cdr x86 ncurses xmms -gtk -gtk2 -gnome alsa -apache -apache2 nptl nptlonly mmx mmxext -xinerama"
CFLAGS="-march=pentium3 -msse -msse2 -O2 -pipe -fomit-frame-pointer -fgcse -fgcse-lm -fgcse-las"
aside from those two variables, my make.conf is pretty much unchanged

[Comment 1 Duncan Coutts (RETIRED) 2006-06-05 10:36:41 UTC]

And you are using gcc-4.1.1 on x86 right?

pasting your emerge --info would be helpful and the exact error message that ghc/ghci reports.

I'm using gcc 4.1.1,

when I run ghc, ghci or hsc2hs my system becomes very unresponsive as the ghc application begins to take up all of my ram, then begins to expand into my swap.

hsc2hs just calls ghc, so I'm not going to post it unless someone thinks it will be helpful

[Comment 4 Duncan Coutts (RETIRED) 2006-06-12 15:24:14 UTC]

Ok, I have managed to reproduce this bug. I'm trying to narrow it down.

[Comment 5 Duncan Coutts (RETIRED) 2006-06-13 02:20:13 UTC]

So I can reproduce this with a stable x86 profile, gcc-4.1.1 and CFLAGS="-march=pentium3 -O2 -pipe"

I'm now trying without the -march=pentium3 bit to see if it's just gcc-4.1.1 that is the problem.

[Comment 6 Duncan Coutts (RETIRED) 2006-06-13 04:06:00 UTC]

Ok I can reproduce it with just CFLAGS="-O2 -pipe" so it looks to be a bad interaction between ghc and gcc-4.1.1. I think we've previously tested with gcc-4.0.x and gcc-4.1.0 but I'm just going to double check.

[Comment 7 Duncan Coutts (RETIRED) 2006-06-13 16:13:24 UTC]

Also reproducable with gcc-4.1.0-r1

[Comment 8 Duncan Coutts (RETIRED) 2006-06-15 05:24:25 UTC]

Fixed! Patch applied in ghc-6.4.1-r3 and ghc-6.4.2. So you'll need to sync and re-emerge from a working ghc or ghc-bin.

Marty, thanks very much for helping us to track down this bug. It now works for me using -O3 and all your other original CFLAGS. If you still find any problems please re-open this bug.
