Hello All,

I was porting one application embedding LuaJIT 2 from WIN32 to WIN64. The application is compiled in Unicode mode. The application crashed in the JIT initialization. The reason comes from the way the pointer to the allocation function is taken in lj_alloc.c. It use the GetModuleHandle() function. This function has two flavors: one with wide chars and one with chars. In LuaJIT, the parameter is always a char string, so when passed on the wide char version of GetModuleHandle() it don't understand the ntdll.dll name, returns a NULL pointer and crashes.

The fix is easy: just use GetModuleHandleA() instead of GetModuleHandle() so that it always use the ANSI flavour whatever we are in WIN64 or WIN32.

Hope this may be helpful to someone.
