I haven't been able reproduce the bug here with free bcc compiler (5.0 I 
guess). I can't link to VCL since it's not included. So I tested two 
dlls, one with Borland's C runtime statically linked and another with 
the runtime linked from a dll. They both worked.

Maybe Borland is setting something and the above code triggers it? I'm 
thinking of something similar to the floating point issues caused by 
DirectX setting a FP flag making Lua lose precision. (not that it's the 
same issue here, merely that it might be something along those lines).
