auth-worker: Error: double free or corruption (fasttop)

Dear list,

since the distri upgrade to glibc 2.28, i can't build working dovecot 
binary's.
Older with glibc 2.27 are working. The distri is LFS based.
MariaDB 10.2.18 and 10.3.11 makes no difference. Having this on 
different systems.

It says "core dumped". Can you obtain a gdb backtrace from those?
