Since you mention using the 2005 express release, did you use any one of
the backward release #defines like
and friends when compiling? I recently had to port over some code from
MSDEV2003/VC7 to MSDEV2005/VC8 and was quite surprised, at how much MS
changed and adapted in between those two releases of their tools.
Specially the silent adaptions in the 64bit pointer departement are
difficult to catch, usually the only thing you see is a port mortem and
a mention of stack corruption.
