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)

I've been sticking to Lua 5.1 on MinGW32...

Anyone has a test program or is the 4.8.x series okay? What about dw2/sjlj effects? The stackoverflow reply sounded pretty confident but lacks certain details...
