Hi All,
	I am using gdb 6.4 on Xscale processor. I found that the backtrace
doesn't terminate for multi-threaded application, it keeps on repeating
the last frame.
This problem was also seen on native gdb.

(gdb) bt

#8  0x400dc0f0 in pthread_start_thread_event (arg=0xbcbffbe0) at
manager.c:310

On  investigating further I found that registers remained unchanged
except sp, for these frames.

Hi Girish,

You need to submit a testcase and a set of steps that people can use to
replicate your problem . I doubt anyone would be able to help you out
without that. 

cheers

Is there anything before this?  This is the start of a thread; there
may be another clone frame on the stack (which we ought to display and
then stop), or there may be nothing on the stack above this.
