Paul Guo created HAWQ-1337:
------------------------------

             Summary: Log stack info before forward signal sigsegv, sigill or sigbus in CdbProgramErrorHandler()
                 Key: HAWQ-1337
                 URL: https://issues.apache.org/jira/browse/HAWQ-1337
             Project: Apache HAWQ
          Issue Type: Bug
            Reporter: Paul Guo
            Assignee: Ed Espino


CdbProgramErrorHandler() is a signal handler, while it seems that it just forwards signal
to its its main thread. This is not friendly for development when encountering signals like
sigsegv, signal and sigbus, etc. We should save the thread stack info in log before forwarding.
