Hi Jean-Pierre,
Replying to [comment:51 jpflori]:

It isn't small.

order to get it closed as wont fix/duplicate because I thought it could be
seen as a concrete example of ticket [ticket:715] and all the work could
be done there.
I am not sure whether it would be good to do everything on one ticket, as
the topics are related, but clearly disting: #715 is about weak
"`TripleDict`" for coercion, #12215 is about a weak version of
cached_function, and the ticket here is about the cache of homsets.
On the other hand: I am about to post a new patch here, with #715 as a
dependency. It will use the new version of `TripleDict` from #715. So, one
could argue that there is a common tool for both tickets, and they belong
together.
Anyway. The new patch will fix the leak, but it will not suffer from the
segfaults.
Cheers,
Simon
