Comment 14 Lukáš Hrázký 2020-10-07 11:18:35 UTC 
Hello Patryk, thanks for the report. Are you able to reproduce this reliably or was it one time only?

If it was a one-time occurrence, it looks like a rare memory corruption bug we are having and are so far unable to pinpoint. There was, however, a fix in libsolv (in version 7.15) recently that might be a possible culprit. It hasn't been released to Fedora yet, but you can get it from our nightly repo:

dnf copr enable rpmsoftwaremanagement/dnf-nightly
dnf update libsolv

If you are getting the crashes at least semi-regularly and were able to tell us the libsolv upgrade fixed it, that would be a valuable information to us.
