(In reply to comment #3)
 Comment #2 indicates that there isn't a problem with a 4.x series compiler .
 I'd like some feedback if this problem exists today with a more recent version
 of the compiler.

I can't reproduce the problem with either gcc-4.3.4 20090405 or gcc-4.4.1
20090428 on an armv5tel-unknown-linux-gnueabi system.

I cannot reproduce this bug with gcc-4.0.4, 4.1.2, or 4.2.0 on an
armv5b-softvfp-linux machine.

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.
