Description Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2017-03-26 13:27:26 UTC
I'm not sure whether it's problem in pycparser itself, or how gajim uses it but after installing it, it doesn't start:

Comment 1 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2017-03-26 13:35:41 UTC
Works after downgrading pycparser to 2.14. The middle version fails the same.
Comment 2 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2017-03-26 13:54:02 UTC
Doesn't happen with dev-python/pycrypto. I wonder if that's a generic bug in pycparser, or sth CFFI-related.
Comment 3 Daniel Robbins 2017-12-25 02:14:45 UTC
Appears to be an issue with pycparser as downgrading to 2.17 resolves the issue. I recommend masking 2.18 until this issue is properly addressed.
Comment 5 Hanno Böck gentoo-dev 2019-05-29 15:21:08 UTC
Is this still an issue?
Comment 6 Amadeusz Żołnowski gentoo-dev 2019-05-30 21:00:34 UTC
I believe it is no longer.
Comment 7 Hanno Böck gentoo-dev 2019-06-01 10:18:14 UTC
Okay, closing this as I believe this is deprecated and only affects older versions.
Please re-open if issue persists with a current system.
