Hello,
One backtrace infinite loop case I've noticed (especially on ia64) is
where successive frames all have a zero PC.
While we definitly need to allow a backtrace through a single zero PC
(for a NULL pointer call - signull.exp) should we make GDB abort when
two or more consecutive frames have a zero PC?
(mumble something about a runtime option)
thoughts?
I still think that you
me or we? Do you have a pointer to the thread?

That sounds like a NULL pointer function call, which is what signull.exp
is all about.
