It might be better at this point to use dwarf2 eh tables to get a
backtrace
than it is from x86's stack frame because if you don't have a frame
pointer,
stack frames are "messed" up.
Mac OS X doesn't support DWARF yet and the compiler doesn't omit frame
pointers (though you can write asm functions which omit them), so for
now regular backtracing code will work fine in nearly all cases.
Unfortunately, MoreBacktrace should handle all cases, not nearly all,
so it'll take a little bit longer before it's ready.
