when compiling the new ghc pre-releases made my gcc 2.95.3 die with "internal compiler error", I tried to compile it with gcc 3.4.3 (or rather, I thought it compiled with 3.4.1, and when that died, compiled+installed gcc 3.4.3, tried again, say it die again and only then noticed it was actually still using 2.95.3 ;) but had quite some difficulty to actually get it to compile with, in my case, /usr/local/bin/gcc3
When using the following command-line
CC=gcc3 CXX=g++3 nice ./configure --enable-hopengl --prefix=/var/tmp/ghc --with-gcc=/usr/local/bin/gcc3
stage1 still used gcc 2.95.3 to compile stage2 (okay, for --with-gcc that's documented)
Really? --with-gcc should set the gcc for stage1, AFAIK. Is there a bug here?
I've noticed gcc 2.95 crashing on my FreeBSD box too. I should look into whether there's a workaround, otherwise we're hosed on FreeBSD 4.x.

In case you've got nothing else left to do.. ;) The ghc command which perfectly repeatable kills gcc: make[2]: Entering directory `/var/tmp/ghc-6.4.20050216/ghc/compiler' ../../ghc/compiler/stage1/ghc-inplace -H16m -O -istage2/utils -istage2/basicTypes -istage2/types -istage2/hsSyn -istage2/prelude -istage2/rename -istage2/typecheck -istage2/deSugar -istage2/coreSyn -istage2/specialise -istage2/simplCore -istage2/stranal -istage2/stgSyn -istage2/simplStg -istage2/codeGen -istage2/main -istage2/profiling -istage2/parser -istage2/cprAnalysis -istage2/compMan -istage2/ndpFlatten -istage2/iface -istage2/cmm -istage2/nativeGen -istage2/ghci -Istage2 -DGHCI -package template-haskell -package unix -package readline -DUSE_READLINE -package Cabal -cpp -fglasgow-exts -fno-generics -Rghc-timing -I. -IcodeGen -InativeGen -Iparser -recomp -Rghc-timing -H16M '-#include "hschooks.h"' -c cmm/MachOp.hs -o stage2/cmm/MachOp.o -ohi stage2/cmm/MachOp.hi /tmp/ghc32662.hc: In function `s5dU_ret': /tmp/ghc32662.hc:11210: Internal compiler error in `build_insn_chain', at global.c:1756 The dying gcc command: gcc -x c cmm/MachOp.hc -o /tmp/ghc15388.raw_s -DDONT_WANT_WIN32_DLL_SUPPORT -fno-defer-pop -fomit-frame-pointer -fno-builtin -DSTOLEN_X86_REGS=4 -S -Wimplicit -O -D__GLASGOW_HASKELL__=604 -ffloat-store -I cmm -I stage2 -I . -I codeGen -I nativeGen -I parser -I /var/tmp/ghc-6.4.20050216/libraries/readline/include -I /var/tmp/ghc-6.4.20050216/libraries/unix/include -I /var/tmp/ghc-6.4.20050216/libraries/base/include -I /var/tmp/ghc-6.4.20050216/ghc/includes The (naively) relevant part of the generated HC-file appears to be the next "function" (with some code which doesn't seem to matter for the crash removed). I have no idea whether this is of any help for nailing this kind of nastiness down, so I'm not going to spend more of my night on it ;) I did attach the complete failing HC-file.
