        <pre>When I access SBThread::frames or use "thread backtrace" in the lldb console,
the stack frame from main function is missing. In the given example, when I set
breakpoint in test, it shows only one stack frame in backtrace. In GDB, it
shows two (test + main). Is this the intended behaviour? How can I access all
the frames? I'm compiling the source with -g and -O0, I even tried
-fno-omit-frame-pointer, but it didn't help.

Example:

void test()
{
   // breakpoint here, bt shows only 1 frame
}

int main()
{
   test();
   return 0;
}</pre>
