[New-bugs-announce] [issue39091] CPython Segfault in 5 lines of code

[Sebastian Krause]

New submission from Sebastian Krause <sebastian at realpath.org>:

The following lines trigger a segmentation fault:

class E(BaseException):
    def __new__(cls, *args, **kwargs):
        return cls
def a(): yield
a().throw(E)
