application core dumps with HPUX ia64
Hello All,
I am trying to run an application that uses Pthread. It core dumps with the a segmentation fault. After loading the the core file in gdb it showed that the "__pthread_cancel_stack()" did a Segmentation fault. I understand this is a Pthread function but I am not sure how to rectify this. Any help in this matter will be greatly appreciated.
The platform is: HP-UX B.11.31 U ia64 3435274391
Thanks and Regards,
Atul.

Re: application core dumps with HPUX ia64
It helps if you show us the stack trace.
Do you have a thread stack overflow?
Have you done a pthread_cancel recently? I.e. is it reasonable to be in your stack trace state?

Re: application core dumps with HPUX ia64
Thanks for the reply. Below is the trace that I get from loading the core file in gdb.
HP gdb 5.9 for HP Itanium (32 or 64 bit) and target HP-UX 11.2x.

Core was generated by `eventsystemtest'.
Program terminated with signal 11, Segmentation fault.

I am running a unittest program that runs well on several other Unix platforms with PThread. That made me wonder if this has something to do with HP-UX and Pthreads.
Thanks and Regards,
Atul.

I only see the top, not a trace. Where is the rest of the "bt" stack trace?
