If true, this is not related to GCC 10 at all. Yes, that really seems a link and/or symbol versioning problem, but it wasn't the only one. I had some other crashes in packages, usually not x86 arches. As an example sord [0] was crashing on power64 when compiled with -O2, an exit condition in a for loop was optimized out until it crashed the loop. I had to use -O1 [1], and I have not tried with gcc 10.1 yet. > Thanks, > Florian Ciao Guido [0]: https://src.fedoraproject.org/rpms/sord/ [1]: https://src.fedoraproject.org/rpms/sord/c/0a9adfc498d2e3cfcb3c8e67e53463beefdb10ff?branch=master
