Bug#1061063: armhf: h5py's tests expose unaligned memory accesses during the build

[Matthias Klose]

Package: src:h5py
Version: 3.10.0-1
Severity: serious
Tags: sid trixie

armhf: h5py's tests expose unaligned memory accesses during the build, 
this not seen with with the 3.9.0 version. You don't see this on the 
Debian buildds itself, because they ignore these misalignments.

Already happens with Python 3.11.
