[Bug target/35180] built-in-setjmp.x2

OK. I decided to look at this in more detail in the simulator.  The failing
instruction is:

 2001358:       d0 07 bf fc     ld  [ %fp + -4 ], %o0

and when I run with a breakpoint there, a dump of the registers shows that fp
is 0!!  When I try to step, it doesn't happen.  If I do a "watch $fp", it never
goes to 0 and runs correctly.

The task has a 256K stack so it isn't blowing it. No interrupts are occurring. 
No context switches are occurring.

Any ideas on how to narrow this down would be appreciated.  Normal debugging
seems to be failing me.
