Could you please try to figure out exactly which optimization option
breaks libalias? It is most likely one of these:
-foptimize-sibling-calls
-fcse-follow-jumps
-fcse-skip-blocks
-fgcse
-fexpensive-optimizations
-fstrength-reduce
-frerun-cse-after-loop
-frerun-loop-opt
-fcaller-saves
-fforce-mem
-fpeephole2
-fschedule-insns
-fschedule-insns-after-reload
-fregmove
-fstrict-aliasing
-fdelete-null-pointer-checks
-freorder-functions
Unfortunately, there's no easy way to do this - you have to turn them
off one by one (e.g. CFLAGS="-O2 -pipe -fno-reorder-functions") and
test the resulting libalias.
