I compiled ACE 5.4.2 with the actual snapshot and got a segfault.

GCC was compiled with CFLAGS="-pipe -g -O3 -mcpu=G5 -maltivec -mabi=altivec -
fmessage-length=0 -falign-loops=16 -falign-jumps=16 -falign-functions=32 -
fstrict-aliasing -fsched-interblock -ffast-math -funroll-all-loops -funit-at-a-
time -fpeel-loops -ftracer -funswitch-loops -floop-optimize2 -fmove-loop-
invariants -fgcse-after-reload -frename-registers -fmodulo-sched --param max-
gcse-passes=5 --param max-unrolled-insns=600 --param inline-unit-growth=300 --
param large-function-growth=400"
