Bug summary

See https://github.com/matplotlib/matplotlib/actions/runs/10361240536/job/28681178039#step:12:209.

This is mostly just a tracking issue to point people to; the error is in compiling contourpy, which is tracked here: contourpy/contourpy#409 but due to a pybind11 issue here: pybind/pybind11#5224

Code for reproduction

Expected outcome

Job compiles.

Additional information

Note that Cygwin is disabled on main as we require Python 3.10 there and only 3.9 is available on Cygwin still.
