I've had better luck x-platform with, e.g.,
assert(!"can't get here"); /* !string is always false */
In non-debug builds, it vanishes so there's nothing for the compiler to
gripe about; while in debug builds most compilers don't do enough flow
analysis to realize there *is* something to gripe about.
Overall, it would be more useful if SGI compilers in particular produced:
C00666: Warning: -O may produce buggy code.
after every executable line <wink>.
