            Bug ID: 15936
           Summary: LLDB incorrectly unwinds a call stack that contains a
                    function with an illegal instruction
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at cs.uiuc.edu
          Reporter: daniel.malea at intel.com
    Classification: Unclassified

When a function has an illegal instruction (as generated by GCC 4.6 for a call
to "__builtin_trap" intrinsic, LLDB does not correctly generate a stack trace.
Specifically, the function that includes the illegal opcode is not present.

See test/linux/builtin_trap/TestBuiltinTrap.py for more details.
