I have definitely seen the problem on 32-bit Linux as well. So I
compile ldo.c specially in luabuild. Here is the relevant part of the
lakefile:
-- gcc 4.6 messes up setjmp/longjmp when optimizing
local ldo = c.group{LDO,defines=defs,args=def,
flags=choose(CC=='gcc','-fno-omit-frame-pointer')
}
(point being that only this file needs the flag, and it may be GCC
version specific)
