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!
