Looks rather like a Mingw problem:

Trunk r118 (last Lua 4 revision) behaves identical to the current Lua 
5.1 trunk revision when compiled with the same Mingw gcc 3.4.2. 
20040916-1 version.

Mingw did change the longjump methods after 3.4.2 and a lot of problems 
were reported due to principal longjump-Windows incompatibilities. Has 
anyone experience with candidate 3.4.5?
