We can now add CPython to this list as 3.13 requires 32-bit alignment [1]: In file included from ../Include/internal/pycore_backoff.h:12, from ../Include/internal/pycore_code.h:474, from ../Include/internal/pycore_interp.h:16, from ../Include/internal/pycore_runtime.h:17, from ../Include/internal/pycore_pystate.h:12, from ../Include/internal/pycore_critical_section.h:9, from ../Python/critical_section.c:4: ../Python/critical_section.c:6:1: error: static assertion failed: "critical section must be aligned to at least 4 bytes" 6 | static_assert(_Alignof(_PyCriticalSection) >= 4, | ^~~~~~~~~~~~~ We should really make the switch now. It's certainly not getting better. Adrian > [1] > https://buildd.debian.org/status/fetch.php?pkg=python3.13&arch=m68k&ver=3.13.0%7Eb1-2&stamp=1715773703&raw=0 -- .''`.
