There are two workarounds suggested on the lua bugs page
(http://www.lua.org/bugs.html#5.1):

   The simplest solution is to use DirectX with the D3DCREATE_FPU_PRESERVE flag
   Otherwise, you can change the definition of lua_number2int in
luaconf.h to this one:

   #define lua_number2int(i,d)   __asm fld d   __asm fistp i
