[issue32421] Keeping an exception in cache can segfault the interpreter

[Julien Palard]

Julien Palard <julien+python at palard.fr> added the comment:

Tested with:

    @memoize()
    def foo(x):
        raise Exception("From foo")


    for _ ∈ range(5):
        try:
            foo(42)
        except Exception as err:
            print(err)

using a python 3.5.4, 3.6.4, and master(13a6c09), and was unable to reproduce it, which version of Python are you using? How are you reproducing it?
