Nick, Remy,

if you use ifstream or similar streams in a statically compiled DLL,
and perhaps in your main executable as well, you may be subject to
collisions of memory management code between the DLL and the main
executable.  I have banned stream I/O from my DLLs for that very
reason.  It is possible that you have to load the DLL at runtime to
make the problem happen (which I do) but I cannot promise that you
have to.

Cheers,              Jochen
