The Guix package fails to build because of a test error (see the last lines of the full build log: https://ci.guix.gnu.org/log/f5if2qb5rsqag3a6jy5vga1l9hm9pkj0-dovecot-2.3.9.3). As the name suggests, this is dovecot 2.3.9.3, the latest version. Previous versions built fine, as well as the same version on x86 and x86_64. Note that the build on guix's build farm was done in a qemu vm, but I got the same test failure on real hardware.

(sorry for the previous mail, client acted up...)

Can you provide backtrace for the core file? This seems to be related to libunwind somehow.
