When Python is built in debug mode, it fails with an assertion error on the following code:
---
def func1():
if a != b:
raise ValueError
def func2():
try
return 1
finally:
pass
---
Try attached pgen_bug.py:
$ ./python pgen_bug.py
python: Parser/pegen.c:68: _PyPegen_check_barry_as_flufl: Assertion `t->type == NOTEQUAL' failed.
Abandon (core dumped)

In release mode, there is no assertion error:
$ python3.10 pgen_bug.py
File "/home/vstinner/python/master/pgen_bug.py", line 6
try
^
SyntaxError: invalid syntax
