I have more crashes in other lines in locator.rs, but probably this are duplicates of this issue

Def agree that we shouldn't be panicking, but is that valid Python code? How would you describe the contents of that file? I'm trying to make sure I'm not misinterpreting the issue.

This is found by fuzzer.
I provided valid python file and changed some bytes/charaters to find possible crashes

Smaller reproducer - a.py.zip

Okay, this is now resolved via #3454 and #3439.
