With a stack trace back i the debugger, you should be able to determine
for which classes code is getting "dropped"

EXPORT assures that code for classes no otherwise referred to doesn't
get "stripped".  But if such code is added to a static library, I doubt it
can be guarenteed that its added to the executable.  I would guess you'll
have to include a module in among your applications which explicitly
refers to this code so it will be sucked into the executable.
