The following compiles fine with gcc 3.3.3:
void f()

"nop\n");

Enter gcc version 3, moving the vtable member to

derived type even if the base type is in C which doesn't know about
vtables.
There are no memory layout guarantees for non-POD types.
If your external functions use the correct type (i.e., a pointer to
the base type), the compiler will automatically cast class pointers in
the correct way. Otherwise, you have to cast to the base type
yourself whenever you 'export' a pointer.
Enter gcc version 4, which requires the templated

code be rewritten in the most nonsensical, misleading and ugly fashion
possibly imaginable this side of Hungary and Redmond, WA, according to
our (now not so very young anymore) hero.
Could you show some details? Probably the old code wasn't quite
correct according to The Standard(TM).
