oops, my mistake. this bug appears on x86 too, at least:
gcc version 3.4.4 20050314 (prerelease) (Debian 3.4.3-13)
fails (at -O2), but:
gcc version 3.3.6 (Debian 1:3.3.6-3)
works. Perhaps this is a bug in SPASS, but the program does
appear to behave as far as valgrind is concerned. Not sure what
sort of legal optimization could break a program in this way. I'm pretty
sure there's no floating-point code affecting control flow here.
