------------------------------
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.
