<pre>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.</pre>
