Re: "double free or corruption (!prev)" during zypper dup download?

I get these double free errors too. The problems started when zypper was updated to version 1.14.45. I downgraded one host to zypper 1.14.42, libzypp.so.1722.3.7 and libboost_thread.so.1.75.0, but the problem persists. The bug might be caused by a library that zypper depends on and that was updated at the same time. I use Tumbleweed in unprivileged LXC containers on a Fedora 34 host with my own kernel and lots of memory-related settings from https://kernsec.org/wiki/index.php/Kernel_Self_Protection_Project/Recommende.... I solved the problem by migrating most containers to Fedora. Thus I am not that interested in debugging the crashes. Kind regards, Andreas
