This is one of the worst bugs of all time. I can't believe this slipped through
the test suite. The top 32 bits of longs is entirely ignored in CTFE == and !=
comparisons. Reduced test case:
====================
int bug8624()
{
  long  m =  0x1_0000_0000;
  assert(m != 0);
  return 1;
}
static assert(  bug8624() );
====================
It's a typo in interpret.c, which results in an implicit conversion from long
to int.
This might be worth an emergency release.
