IPO+openmp = segfault ?

Hi,
I have been having some issues where when I compile a code with openmp and the ipo flag, I obtain segfaults when I scale up the program. It works fine when I don't use openmp. This is a rather large program, so I can't post a source file, but if any one has insights I would appreciate it.
Thanks,
Ted

Have you tried increasing the stack size for the program?

How many OpenMPthreads are created? (You could monitor it inthe Task Manager )

How much memory the application used? ( The same as above... )

Could you provide more technical details for a Windows platform?

Best regards,
Sergey
