The same problem occurs with boost171 @1.71.0_8 with the +python312 variant.

Replying to ar-an-ribe:

The same problem occurs with boost171 @1.71.0_8 with the +python312 variant.

For use in make_instance.hpp with Python 3.11 or newer, it looks like ​Py_SET_SIZE would be a suitable replacement for Py_SIZE. A comparison of the changes in make_instance.hpp between ​Boost 1.71.0 and ​Boost 1.85.0 could be the basis of an appropriate patch for Boost 1.71.0 with Python 3.11 or newer.
