[New-bugs-announce] [issue42206] Pegen: Raise errors occurred by the AST validator

[Batuhan Taskaya]

New submission from Batuhan Taskaya <isidentical at gmail.com>:

When working on the AST validator, it is unclear that which of the changes caused parser to fail on valid input. I propose to propagate the error and raise it.

Current:
$ ./python t.py
python: Parser/pegen.c:1146: _PyPegen_run_parser: Assertion `PyAST_Validate(res)' failed.

Proposed:
$ ./python t.py
ValueError: Test AST error raised by the Python/ast.c
