Línea de trabajo
Comienza reproduciendo la secuencia de Julia REPL con Revise y PyPlot que se muestra en el issue. Lee src/visit.jl y src/packagedef.jl de Revise y, después, src/PyCall.jl de PyCall alrededor de pydecref, y compáralos con los stack frames de Julia 1.12 y Python indicados. La tarea estará terminada cuando el segmentation fault reproducible esté aislado y ya no se produzca en la configuración demostrada.

Descripción
I have been using PyPlot (with PyCall) with Revise.jl quite well in the past years, but after the upgrade to Julia 1.12 I see now constant crashes. I've tried to debug these, but they happen quite randomly. I was about to point the issue as happening only in IJulia kernels, when I started seeing them in Julia REPL as well.
These crashes can happen whenever, and are not related to calling "plot" functions.
I have tried reinstalling PyCall and PyPlot with ENV["PYTHON"] = "" (today) and verified the installation happens with a clean Conda.jl environment.
Here is an example of simple commands that trigger the crash:
$ julia
