I was able to test reportlab with the 3.12.0a5 release (I build following the Archlinux pkgbuild), but am unable to do 
so with 3.12.0a6 because of problems with cython/lxml/freetype-py (I think).

With an optimized build of a6 I was getting segfaults which I think were caused by incompatible C extensions from the 
pip cache so decided to rebuild the requirements.

With latest cython git (allegedly 3.0.0b1) I see errors related to tstate eg


> Cython/Compiler/Parsing.c:86861:34: error: ‘PyThreadState’ {aka ‘struct _ts’} has no member named ‘curexc_traceback’
> 86861 |         PyObject* tmp_tb = tstate->curexc_traceback;

I guess that this is caused by changes in what we are allowed to see of Python internal structure.

If anyone knows of a way to advance further I can try to experiment.
