Test case for PR26463

I can confirm this bug with both gcc-3.3.6 and gcc-3.4.5,
on armv5b-linux. I've added a simple test case that instead
of crashing due to the stack being clobbered, prints an
error message and exits with 1 if the bug occurred.

This is a very nasty error. A fix, even if only to disable
some broken code in gcc, would be very welcome.
