somebody is touching a dead object to decref it.
Not sure what you exactly mean.
What I meant is that Sage was already decrefing objects too much before
the patches here, so maybe we did not add anything wrong here, except that
random segfaults which could already have happened before now actually do.

that enable all this debugging if I compile with `SAGE_DEBUG=yes`? We
should push this out into a beta first, then people can actually look at
their own code and see if it does something wrong.
I got one for Python on my computer...
I've opened #13684 (the spkg is not there yet, it will be when I attach
the diff).
