Hi all.

For the record in case someone gets a chance over the weekend, I've narrowed
the optimisatios which may cause a crash down to just a few:

| I will also break the optimisations down into their individual components
| per your earlier suggestion.  The above three tests suggest

Working with GCL stable branch, gcc 3.3.3, binutils 2.15.90, PIV 512 MB
WinXP, the ANSI test builds with 305 errors if


O3FLAGS = -fdefer-pop -fmerge-constants -fthread-jumps -floop-optimize \
 -fcrossjumping -fif-conversion -fif-conversion2 -fdelayed-branch \
 -fguess-branch-probability -fcprop-registers -fomit-frame-pointer \
 -fforce-mem  -foptimize-sibling-calls -fstrength-reduce -fcse-follow-jumps
 -fcse-skip-blocks -frerun-cse-after-loop  -frerun-loop-opt \
 -fgcse   -fgcse-lm   -fgcse-sm -freorder-blocks -falign-functions \
 -falign-jumps -falign-loops -falign-labels \
 -fdelete-null-pointer-checks -fexpensive-optimizations -fregmove \
 -fschedule-insns  -fschedule-insns2 -fsched-interblock -fsched-spec


Adding this group of optimisations causes the ANSI test build to crash:

#          -fcaller-saves \
#          -fpeephole2 \
#          -fstrict-aliasing \
#   -freorder-functions \


I'll try and narrow this down over the weekend but no guarantees so please
feel free to investigate and let us know!
