I just pushed a change to reduce the stack memory usage when deleting a chain
of exceptions in bpo-44348. I consider that this issue is a duplicate. If it's
not the case, please reopen the issue.

bpo-44348: BaseException deallocator uses trashcan (GH-28190)
The deallocator function of the BaseException type now uses the
trashcan mecanism to prevent stack overflow. For example, when a
RecursionError instance is raised, it can be linked to another
RecursionError through the __context__ attribute or the __traceback__
attribute, and then a chain of exceptions is created. When the chain
is destroyed, nested deallocator function calls can crash with a
stack overflow if the chain is too long compared to the available
stack memory.
