Yeah, cassert is expensive (mostly it's the CLOBBER_FREED_MEMORY part,
which you can disable separately if you have a mind to). --enable-debug
is supposed to be free when using gcc, though I've never tried to verify
that. We can *not* make --enable-debug the default on non-gcc
compilers, though, and that makes me uncomfortable about turning it on
by default for gcc ... platform-specific defaults don't sound good.
