I guess this could have something to do with the fact that GCC and MSVC
could be using different versions/copies of msvcrt.dll, and each one of
the DLLs has different stacks, heaps, etc. This leads to funny things
like the fact that you cannot malloc() memory using one copy of the
library and free() it with the other one -- because their “view” of
what's in memory is different.

For some more info on this, consider reading the “Windows and the C
runtime DLLs (msvc*.dll)” section at the BuildingModules page from
the Lua-users wiki [1].

Hope this helps :)
