libyaml-based builds segfault on Python 3.13.0a1 #761

Open nitzmahone opened 8 months ago

nitzmahone commented 8 months ago

Fails on Linux x86_64 when built under Cython 3.0.3 (w/ distutils compat hack) and Cython 0.29.36. Suspecting this is a Cython upstream issue...

Building with https://github.com/cython/cython/pull/5767 gets us a little closer- no more segfault, but still blows up on import with various missing symbols; I fixed PyThreadState_GetUnchecked locally, but there are several others that are still broken.
