Looks interesting but there is no documentation on how to use!

@MaxwellDupre Thanks. I add comments to explain how to use

Dump current interpreter frame's code in lldb/gdb command:

(lldb) exp _PyCode_DebugDump(frame->f_code, "debug")

Or Insert the code where you want to observe debug mode:

#ifdef Py_DEBUG
    PyCode_DUMP_IF(code, "foo", "foo", "foo.py");
#endif
