pypdf hangs on one specific PDF - cannot catch error with try/except

[amplicity]

pypdf freezes on one specific PDF. I get no error, and no succeed. I am not able to see what the error is.

Environment

Which environment were you using when you encountered the problem?

$ python -m platform
macOS-12.3.1-arm64-arm-64bit

$ python -c "import pypdf;print(pypdf.__version__)"
3.8.1

Code + PDF

This is a minimal, complete example that shows the issue:

from pypdf import PdfReader

reader = PdfReader("example.pdf")
number_of_pages = len(reader.pages)
page = reader.pages[0]
text = page.extract_text()

The PDF is shared below. This is a publicly-accessible PDF.

MiFO_LFO_FEIS_NOA_Published (3).pdf

Any thoughts as to why this particular pdf might hang?

The fix was just merged and will be part of pypdf >= 3.9.0. It will be released today. A regression test was added.
