Dead-lock in MYSQL_BIN_LOG::reset_logs(..) ?

I've installed MariaDB 10.3.7 and initialized with my own configs (from previous setups), set a root user.. etc, then I have executed

/usr/bin/mysql -NAB -u'root' -p'!password$$' -e "RESET MASTER"

And this command seems to be stuck since hours (actually it is almost half a day since now...).

I have attached my mysqld config, logs and the backtrace of mysqld too, it seems to be waiting for a mutex ... possibly dead-lock internally?

Actually there are two issues here:
1) Server gets stuck in executing 'RESET MASTER'
( The GDB backtrace suggests it is waiting for a mutex, possible dead-lock? )
2) Client never times out? how is that?
( I still have this running since yesterday ~15:16 or something like that... )

Unfortunetely mariadb doesn't provide -dbg packages (or i just don't see them) so i couldn't provide better backtrace atm...
