singular could be involved with that.
Sure.
So, what shall we do? Do we all agree that the plan is as follows:
* The SIGALRM problem (under gdb) is solved on a different ticket
already, namely #13437. So, make it a dependency.
* The refcounting problem that is likely to be behind the signal 11
problem (without gdb) can be temporarily worked around by using a strong
cache to libsingular polynomial rings. I only wonder whether the doctests
demonstrating the weak cache will still work. But it would be a chance to
finally get over with #715 and #11521 and #12215 and #13370 and #12313 and
#12876 and so on.
* A proper fix of the refcounting problem should be done on a new ticket.
Nils, since you already made a deep analysis of the problem, could you
create that new ticket?
Here is another message to the patchbot, since I forgot to include the new
patch:
Apply trac_715_combined.patch trac_715_local_refcache.patch
trac_715_safer.patch trac_715_specification.patch
trac_715_osx64-dealloc.patch
And then #11521
