Description

I've reduced the problem to the following testcase...

[vitek@jenga tests]$ cat t.cpp; aCC -g t.cpp; gdb a.out
extern "C" {
  typedef void rw_signal_handler_t (int);
}

rw_signal_handler_t* const rw_sig_ign = (rw_signal_handler_t*)-2;

unsigned rw_alarm (rw_signal_handler_t* handler)
{
  if (rw_sig_ign == handler) {
    return 4;
  }

  else if (handler) {
    return 5;
  }

  return 0;
}

extern "C" {
  void my_signal_handler (int) { }
}

int main ()
{
  rw_alarm (my_signal_handler);

  return 0;
}
