You are right, 3.7.3-4 from jammy already contains the fix. I am suspecting that the fix might be the cause of your segfault since this was the last change in this part of the code and it seems to be a regression introduced in jammy.
It looks like this bug hasn't been reported upstream yet. so we should probably take the discussion there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1974214 Title: Segfaults on verify callout, in _gnutls_trust_list_get_issuer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/exim4/+bug/1974214/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
