I think I can answer this now. Previously, python-meshio was writing
and reading STL files in native byte order, so the STL test passed on
big-endian systems. However, the data should have been in
little-endian byte order [1], so python-meshio was creating invalid
STL binary files on big-endian systems.
Upstream caused the files to be written in little-endian byte order in
commit 59a19d1. All that was missing was for the files to be read in
little-endian byte order as well. I submitted a PR and it was
accepted.
