Comment (by SimonKing):
One rather puzzling error:
{{{
sage: import gc
sage: SG4 = SymmetricGroupAlgebra(ZZ,4)
sage: gc.collect()
1051
sage: SG4(1).is_central()
------------------------------------------------------------------------
./sage: Zeile 134: 14576 Speicherzugriffsfehler "$SAGE_ROOT/src/bin/sage"
"$@"
}}}
Why is this puzzling? Well, it does not occur when I make both domain and
codomain weak references, for coerce maps. But it ''does'' occur when I
only make the domain a weak reference.
So, is it the case that "the more weak references, the more crash safe"??
