# Bug report
`Parser/pegen.c` and `Tools/peg_generator/peg_extension/peg_extension.c` contain checks for wrong macro:
```c
#if defined(PY_DEBUG)
```
They always false, because the correct name is `Py_DEBUG`, not `PY_DEBUG`. Therefore, the code which was supposed to run in the debug build, is never compiled code.
