The following compiles fine with gcc 3.3.3:

void f()
{
        __asm__ ("nop\n"
                 "nop\n");
}

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.

Could you show some details?  Probably the old code wasn't quite
correct according to The Standard(TM).
