I have spent some time looking at this and I'm more inclined to think
about that this issue has nothing to do with python3.12.

The error from (lib)nauty, unfortunately I did not find the root cause.
The error prototype is defined:
https://salsa.debian.org/science-team/nauty/-/blame/master/nauty.c?page=2#L1175

pynormaliz use libnormaliz that defined some header files in
/usr/include/libnormaliz/ which has relative with nauty.


https://tracker.debian.org/pkg/nauty

So I suspected the root cause is that upgrading of nauty. If someone
help me to understand the specially call chain or debug method I'm
appreciate it.

Thanks.

In fact even on python3.12 the pynormaliz package can be built with nauty 2.8.6+ds-2. Now the failed version is on nauty 2.8.8+ds-1. So if you look at the update for nauty and then have a better understand:
