The following warnings are raised with Cython 3.0.10 and Python 3.12.2:

[1/1] Cythonizing src/silx/image/marchingsquares/_mergeimpl.pyx

Closing, this looks to be an issue in cython: https://groups.google.com/g/cython-users/c/q5FzO2d88Og

Reopening just to make sure this comment is read.

That reminds me of a very similar warning when building fisx...

Have you tried to make sure the methods wrapped with except + are nogil compatible?

Having a second look at this issue, it does change the generated C++ code (see PR #4110)
