getting stacktrace from core dump

How can I get a stack trace from a core dump file? The file is about 14 mb and is generated after my application exits saying "segmentation fault"

I'm on Red Hat 5.5

Solution 
  • gdb /usr/bin/myapp.binary corefile

    Then, use one of:

    (gdb) bt
(gdb) bt full
(gdb) info threads
(gdb) thread apply all bt
(gdb) thread apply all bt full

    Note that installing debug symbols for the related libraries will help
