in a related tangential note, i recently found (out of sheer irritation)
in less than an hour that several (including the latest) versions of GCC
-O and -O2 failed the paranoia test in different ways, to wit:
gcc -o paranoia paranoia.c
[paranoia output elided]
The number of DEFECTs
Add the -ffloat-store flag to your compilation flags (or
add -msoft-float).
that really means for this compiler on certain platforms, you
can have slow and correct or fast and incorrect, but NOT fast
and correct.
