That's the double free error origin. I was able to download the source code from there, build it and patch it and now it shows the following error on syslog:
Jul 23 13:15:02 izanagi fprintd[98658]: Device reported an error during verify: Response had wrong subcommand type
Jul 23 13:15:26 izanagi fprintd[98658]: Device reported an error during verify: Response had wrong subcommand type
About the PAM module issue, I followed Benjamin changes and this one is a bug:

Which matches the last message from Benjamin about the subcommand f0: https:/ /bugzilla. redhat. com/show_ bug.cgi? id=1832229# c57
I will try to debug it in the next days, If I find something I will report it here.
