[LuaJIT FFI] Crashing when exiting after loading SOIL DLL

[Alex <initrd.gz@...>]

I'm having issues with loading SOIL (
http://www.lonesock.net/soil.html ) via LuaJIT 2 beta 9 FFI. The
library works and loads textures, however, when the script finishes,
the luajit interpreter crashes. Upon termination, the windows
"luajit.exe has stopped working" window appears, with the following
information:

Problem signature:
  Problem Event Name:	APPCRASH
  Application Name:	luajit.exe

I've searched for a solution on Google, but didn't find anything
relevant. I've updated MinGW, but no help. GDB didn't provide any
special output, other than the fact that the program exited with
return code 03.

The SOIL DLL that I am using: http://dl.dropbox.com/u/10658954/SOIL.dll
The header I am using with ffi.cdef: http://dl.dropbox.com/u/10658954/soil.h
I'll be happy to post any more information as needed.
What may be going wrong here, and how can I fix this?
