Comment:
Good news! With the new patches, i.e.
{{{
$ hg qa
trac_715_combined.patch
trac_715_local_refcache.patch
trac_715_safer.patch
trac_715_specification.patch
trac_11521_homset_weakcache_combined.patch
trac_11521_callback.patch
trac_13447-consolidated_refcount.patch
trac_13447-modulus_fix.patch
trac_13447-rely_on_singular_refcount.patch
}}}
there is only one crash with make ptest, namely
{{{
sage -t -force_lib devel/sage/sage/libs/singular/groebner_strategy.pyx #
Killed/crashed
}}}
The crash seems harmless, this time: It occurs at `strat =
GroebnerStrategy(None)`, and I suspect that the attempt to incref "None"
is a bad idea...
While we are at it: Perhaps it would be better to ''not'' unmerge #13145,
but to use it as a dependency.
