A testcase which is exposed by PR 22368's second patch:
int __show_backtrace(void *rw)
{
  return (rw  (((unsigned long) rw) = 0xf000) );
}

Confirmed, reduced testcase:
void __show_backtrace(void *rw)
{
  while(rw  (((unsigned long) rw) = 0xf000) ) {}
}

looks like a fold bug with respect of type issues.  This is target independent.

And here is a testcase which fails on LP64 targets:

void __show_backtrace(void *rw)
{
  while(rw  (((unsigned long) rw) = 0xf000) ) {}
}

Deity on a crutch!  That was fast.
Thanks; I can test if you like, or just wait for the next snapshot.
