Bug report

Bug description:

I mentioned regex but this probably applies to other modules as well. In the code below, if the# line right after the findall is commented out (as it is right now), the code raises the exception past the try-except block on theprint("Safely reached EOF.") statement. The exception happens one statement later than expected. NB: I tested all Python versions on Windows but only 3.11 on Linux.

CPython versions tested on:

3.9, 3.10, 3.11, 3.12, CPython main branch

Operating systems tested on:

Linux, Windows
