Description
Bug summary
On current main, clicking on the subplot tool the additional figure pops up and can be interacted with properly, however when clicking the close button the app crashes with a segfault. Possibly trying to release an object that has already been released/garbage collected previously... I can only reproduce this by clicking the subplot button. Manually callingfig.canvas.toolbar.configure_subplots() seems to work fine when closing that window. Perhaps we need an explicit retain on the objc side...
This was brought about by the change to ARC in#23060. I'm going to put the release critical label on it, because a segfault seems worse than memory leaks. Probably smart to revert#23060 if no one has an immediate fix for it.
Code for reproduction
importmatplotlib.pyplotaspltplt.figure()plt.show()
