Consider this function, which has a syntax error on line 4.

>>> def f():
...     try: 
...         1/0
...     except:
...         pass
...     except Exception: 
...         pass

3.9 reports an incorrect line number of 3.
3.10b reports an even more incorrect line number of -1.

Although I've marked this as a "Parser" bug, the offending code is in the compiler.

For 3.11, this is fixed by https://github.com/python/cpython/pull/25729
