Dear All,


As we know, generally, we run bt command in gdb, gdb show the seg fault
location in last backtrace.

I found one strange behaviour If i run? bt command in gdb, at that itme, gdb
didn?t show the segment ?fault location in backtrace by default.

Can some one tell the reason
and is this expected in SMP

Looking at your registers names, looks like the processor is not Intel's, right?

But anyway, looking further at your backtrace, which (seems?) ended in
malloc consolidation, I smell one suspect...double free()....

So, may I ask, do you inaccidentally did that?

Quite likely in such condition, stack frame is also corrupted, so you
will find less valuable...or even worst, no valid information there.
