Comment (by SimonKing):
If one replaces _unsafe_deallocate_pari_stack by `__dealloc__` (as
suggested by #12215), the segfault created by manually using quit_sage()
has moved to `sage.rings.integer.clear_mpz_globals()`. I guess that
function has to do some checks before calling free.
Anyway. With the change to pari, one still has the signal 11 problem in
sage -t sage/misc/cachefunc.pyx, as before.
