Help needed for gdbserver and pthread on Redhat 9

Help needed for gdbserver and pthread on Redhat 9

[Ming Sun]

If I have a break point in the entry function of a thread, when 
pthread_create() is
invoked my program receives a SIGTRAP signal and quit. The gdbserver 
outputs
"Cannot find new threads: generic error" before it breaks at main() also.
Is this normal or there is some configuration I need to do?
 
Thanks for the help,

Ming

I answered this question yesterday: it's probably a problem with NPTL. 
There's not much more advice I can give you.  Red Hat developers may
have more of an idea.
