Comment (by SimonKing):
Hm. With sage-5.0.beta13 plus #715, #11521, #12875, #12877 and [attachment
:trac_12876_category-fix_abstract_class-nt-rel11521.patch], I get one
error, namely a segfault in
{{{
sage -t -force_lib
"devel/sage/sage/rings/number_field/number_field_rel.py"
}}}
But strange enough: When I ran it with --verbose, all tests passed, and
the segfault came from leaving sage. That reminds me another problem: The
deallocation of the (unique) pari instance is not done as it is supposed
to be. This is fixed by the second patch of #12215. Hence, I am trying
again, with #12215 added.
