Description
The problem was originally found with this tree: https://github.com/Buggynours/MariaDB, but it's also reproducible with the main MariaDB tree git@github.com:MariaDB/server.git with the 10.0 branch.
The 5.5 branch in git@github.com:MariaDB/server.git works without problems.
I configure MariaDB as follows:
cmake . -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=/opt/mariadb-10.0 -DWITH_CONNECT_STORAGE_ENGINE=1
then do make && make install followed by mysql_install_db.
Now if I run mysqld and try to connect using a non-privileged user, mysqld crashes on assert with the following output:
bar@lxOtto:/opt/maria-git/MariaDB/sql> ./mysqld

This could be because you hit a bug. It is also possible that this binary
|
or one of the libraries it was linked against is corrupt, improperly built,
|
or misconfigured. This error can also be caused by malfunctioning hardware.

|
We will try our best to scrape up some info that will hopefully help
|
diagnose the problem, but since we have already crashed,
|
something is definitely wrong and this may fail.

|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467212 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
|
information that should help you find out what is causing the crash.
|
If the first connection is done by "mysql --user=root test", then it works fine, so do all further non-privileged connections.
If I do the first connection with a non-privileged user using "mysql -A test", it works fine, however the next connection "mysql test" crashes again.
