Thanks for that. None of the -f flags seems to affect anything.
foundBugs $ cat flag.list
--param=early-inlining-insns=14
--param=inline-heuristics-hint-percent=600
--param=inline-min-speedup=15
--param=max-inline-insns-auto=30
--param=max-inline-insns-single=200
-O2
foundBugs $ ~/gcc/results/bin/gcc -w -O2 bug998.c && ./a.out
checksum = 77A231E6
foundBugs $ ~/gcc/results/bin/gcc -w `cat flag.list` bug998.c && ./a.out
checksum = 130B5204
foundBugs $
So it looks like one or more of the --param flags is to blame.
