dnf crashes ~60% of the time in this container, but in different places. So it seems to be some memory corruption issue.

Hi,

are you able to provide us a coredump with the exact versions of dnf, hawkey and librepo? Do you experience this only in containerized environment?
Comment 3 Zbigniew Jędrzejewski-Szmek 2015-08-11 10:18:02 EDT
I cannot reproduce this anymore. Unfortunately I have upgrade dnf to dnf-1.0.2-3.fc24.noarch in the mean time which might be related, but again might not.
