--- Comment #1 from Nathaniel Shead <nshead at gcc dot gnu.org> ---
Confirmed. Issue is specifically when doing 'import A' before 'import :Part';
the other way around things work fine.
Difference seems to be because when we first see C through A, we don't bother
re-importing through :Part, and so we don't include the linemap table within B.
But because we still consider it to be a direct import (via :Part), when
attempting to read the import location we fail because we haven't loaded its
linemap entry yet.
I expect a solution will probably be to adjust B to include the linemap entries
for direct imports also via partitions.
