I'm really sorry, but it was a long day yesterday. I forgot to mention that I used alpine:edge (based on the alpine master branch) image to set up the build environment. So there were some version changes.
dovecot --version: 2.3.3 (dcead646b) apk info musl: musl-1.1.20-r2 description: the musl c library (libc) implementation Configuration was unchanged wrt to my first mail. Maybe it's helpful to share the build flags? export CFLAGS="-O0" export CXXFLAGS="$CFLAGS" export CPPFLAGS="$CFLAGS" export LDFLAGS="-Wl,--as-needed" In the APKBUILD file can be found here: https://git.alpinelinux.org/cgit/aports/tree/main/dovecot/APKBUILD and I've modified the following: options="libtool !strip" subpackages=" .... $pkgname-dbg " And if it is of any interest, I've done a `docker commit` on the container and pushed the resulting image as muhlemmer/dovecot:debug. https://cloud.docker.com/repository/docker/muhlemmer/dovecot/tags. Don't know if its of much use by itself, without the Mailu ecosystem around. Just in case. Cheers!
