So, with 1.0.4-1 the build seems to be reproducible, in the sense that
it generates the same two
sas64_constrained_ellipsoid_7FA82C95.so
sas64_constrained_ellipsoid_9F860665.so
each time.
Not obvious to me why there is a double provisioning of
sas64_constrained_ellipsoid. They're both generated right at the
beginning of dh_auto_install (running build_py, before running
install_lib). None of the other compiled_models are listed at that
point.
All the other compiled_models are built earlier, during
override_dh_auto_build.
It must be related to the _constrained_ property. The actual model is
just "ellipsoid", "sas64" and "constrained" are build tags. No other
model is built as "_constrained_", only ellipsoid. So it might be that
_7FA82C95 and _9F860665 distinguish between two distinct constraint
conditions.
