Description Jonas Jelten 2019-02-03 16:23:11 UTC

gdbm_close of >=sys-libs/gdbm-1.17 also sets gdbm_errno. This overlays a value that is used for returning a lookup failure.

Can confirm that the patch works and restores the ability to migrate cyrus-sasl from berkdb to gdbm (which otherwise fails with very misleading auth errors).
My system is now completely berkdb-free. Thank You!

FWIW, this patch did actually get added at some point: https://gitweb.gentoo.org/repo/gentoo.git/commit/dev-libs/cyrus-sasl?id=0ea0e5c7d34102447316e0ec3e9a4aa82e4523bf
