[issue5223] infinite recursion in PyErr_WriteUnraisable

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <amauryfa at gmail.com> added the comment:

python 3.0 does not crash. And it has better code for infinite recursion
(r55850, r66186)
I suggest to backport the py3k code, patch attached.

Martin, your comments are welcome. Are there compatibility issues?
