Oooh, I suggest you use /opt
./configure \
--prefix=${PREFIX} \
--sysconfdir=/etc/opt/${PREFIX} \
--localstatedir=/var/opt/${PREFIX} \
...
$ man -s 5 filesystem
$ mdb test-http-auth core

Spot the zeros. It's doing the equivalent of 'vsnprintf(s, "%s", 0);'.
The check will run by changing the test code and not attempting to print
nulls, patch file attached. I've not thought about this deeply and this
is no more than a hack to get the test to run, I didn't study the result.
On face value the core dump says dovecot has failed the test because its
string functions don't take nulls, that is if dovecot ever sends them
nulls which I can't say other than dovecot does run without dumping
core. If there is the possibility nulls need to be printed the dovecot
functions in src/lib/strfuncs.c need fixing.
