Interestingly, I can turn all the "-f" flags off and it still doesn't segfault. However, if I omit the "-O2" but turn all the "-f" flags on, it always does segfault. So the offending optimization appears to only depend on "-O2" and not on any of the flags implied by -O2: # GNU C version 3.2.2 20030222 (Red Hat Linux 3.2.2-5) (i386-redhat-linux) # compiled by GNU C version 3.2.2 20030222 (Red Hat Linux 3.2.2-5). # options passed: -fpreprocessed -O2 -Wall -fverbose-asm # options enabled: -fdefer-pop -foptimize-sibling-calls -fcse-follow-jumps # -fcse-skip-blocks -fexpensive-optimizations -fthread-jumps # -fstrength-reduce -fpeephole -fforce-mem -ffunction-cse # -fkeep-static-consts -fcaller-saves -fpcc-struct-return -fgcse -fgcse-lm # -fgcse-sm -frerun-cse-after-loop -frerun-loop-opt # -fdelete-null-pointer-checks -fschedule-insns2 -fsched-interblock # -fsched-spec -fbranch-count-reg -freorder-blocks -fcprop-registers # -fcommon -fverbose-asm -fgnu-linker -fregmove -foptimize-register-move # -fargument-alias -fstrict-aliasing -fmerge-constants -fident -fpeephole2 # -fguess-branch-probability -fmath-errno -ftrapping-math -m80387 # -mhard-float -mno-soft-float -mieee-fp -mfp-ret-in-387 -mcpu=i386 # -march=i386 Thanks, -Archie __________________________________________________________________________ Archie Cobbs * CTO, Awarix * http://www.awarix.com
