--- Comment #4 from Tobias Burnus <burnus at gcc dot gnu.org> 2010-11-03 07:37:54 UTC ---
I did some debugging and found out that I only see the ICE on x86-64-linux if I
use:
export MALLOC_PERTURB_=$(($RANDOM % 255 + 1))
(current value: 191)
If I do not set that variable, xgcc compiles gcc/sched-rgn.c without an ICE. I
tried valgrind, but it shows no error.

Also affects i386-pc-solaris2.10, sparc-sun-solaris2.10, mips-sgi-irix6.5.
Proposed patch allows bootstrap to continue on Solaris 10/x86, but later rans
into
another ICE:
/vol/gcc/src/hg/trunk/local/gcc/config/i386/i386.md: In function 'split_insns':
/vol/gcc/src/hg/trunk/local/gcc/config/i386/i386.md:11856:1: internal compiler
error: in dwarf2out_frame_debug_adjust_cfa, at dwarf2out.c:1881
(maybe related to PR bootstrap/46018).
