In #7269, the undefined symbol was in _imaging.so, so I do think that's different. Allow me to try and understand - you've pasted the features/report info, showing the Pillow installation...

If you just run ```python from PIL import Image im = Image.new("RGB", (1, 1)) im.save("out.tif", compression="jpeg") ``` does the error occur?

Having a GitHub Actions reproduction is definitely helpful. I haven't had as much time as I would like to investigate this, but here are my thoughts so far. The fact...

[`io.BytesIO`](https://github.com/radarhere/sphinx_demo/commit/17e18c6ad73ab66c8ca22330217283e74b3f5288) [doesn't actually make a difference.](https://github.com/radarhere/sphinx_demo/actions/runs/10751703505/job/29819236632#step:6:32)
