            Bug ID: 25061
           Summary: Thread doesn't contain the main stack frame
           Product: lldb
           Version: 3.6
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P

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.


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

int main()
   return 0;
