That's not a compiler bug. That means your code is not portable.

This code will compile on some UNIX platforms, but not on GNU/Linux:

  #include <sys/mman.h>
  caddr_t* p = 0;

But that's not a GCC bug, it's because the code is not portable.

Anyway, if you think it is a bug you need to follow the bug reporting
instructions.
