then we'll deal with that ... we're trying to debug bad code, not bad code

why ? -fomit-frame-pointer is only used with -O whenever it doesnt interfere
with debugging ... in other words, -O on x86 will not imply
-fomit-framer-pointer
and as noted, x86_64 doesnt suck like x86, so this isnt an issue for amd64 :)
