Minimal example tree.cc:
...
extern void iterative_hash (const int *);

unsigned int
iterative_hash_expr (unsigned int val)
{
  int code;
  switch (val)
    {
    default:
      iterative_hash (&code);
      return 0;
      break;
    }
}
...

to reproduce:
...
gcc -Werror -Wreturn-type -O0 tree.cc -S -fno-exceptions
...
