Comment (by SimonKing):
Hi Nicolas,
I was about to create a reviewer patch. But I am afraid ''the same''
problem creped back in sage/rings/polynomail/multi_polynomial_sequence.py.
In other words: When I have a weak cache on dynamic classes, then the
double free occurs in crypto/mq/mpolynomialsystem.py, but when I have a
strong cache, then the double free occurs in
rings/polynomial/multi_polynomial_sequence.py (but again in a test
involving polynomial systems!).
I have a preference for a weak cache, and since apparently the weak cache
as such is ''not'' to blame for the error, I need to look somewhere else.
Perhaps there is some `UniqueRepresentation` in mpolynomialsystem.py that
needs a strong cache. If that turns out to be correct, then I will do the
necessary change in #12215.
Apart from that: I will be away until Monday as well.
