Pointer to members usually cause this kind of problem. You have to be very 
careful, since the sizeof may not be the size of a pointer. See:

$ cat > file.cpp
class A { void f(); };
int main() { typedef void (A::* pmf)(); return sizeof(pmf); }

$ g++ -o file file.cpp
$ ./file; echo $?
8

This was on a 32-bit architecture.
