Crash in ~FzColorspace() #3869

Open qu1ck opened 1 month ago

qu1ck commented 1 month ago

Description of the bug

Not sure if this should be reported in mupdf repo instead, please let me know.

How to reproduce the bug

The trigger for this crash is somewhat convoluted. KiCad EDA package uses python scripting for it's plugins and this was discovered when one plugin is launched while another plugin that uses pymupdf is present in the installation. Original bug report is here: https://github.com/openscopeproject/InteractiveHtmlBom/issues/467

After looking at the crash it's apparent that none of the plugins have anything to do with the crash, it happens when python garbage collects some objects and in particular FzColorSpace causes the crash.

By bisecting the pymupdf version I found that last one that does not crash is 1.23.8. Crash reproduces reliably.

PyMuPDF version

1.24.10

Operating system

MacOS

Python version

3.9

Thanks for the detailed report.

We have a theory about what's going on, i'll update this ticket in the next few days hopefully.

julian-smith-artifex-com commented 1 month ago

Unfortunately my theory didn't work.

One thing to point out, is that the crash log has many threads, but PyMuPDF does not support use by multiple threads. Is this likely to be a problem here?

qu1ck commented 1 month ago

There are many threads because it's a gui cpp application, but only the main thread is running python interpreter so that should not be an issue.
