Subject: [PATCH] Catch System Error in ast parse (#20961)

I can't seem to reproduce, but i got this:

```
SystemError: AST constructor recursion depth mismatch (before=102, after=37)
```

And the operation isn't critical for the actual forward pass so seems
preferable to expand our caught exceptions
