CentOS7 (standard Google Compute Engine image)
Description
MariaDB server crashes when I select from a CONNECT table of type ODBC that uses the MySQL 5.3 ODBC connector. Note that I CAN select from a CONNECT table that uses ODBC and FreeTDS driver, and that both the FreeTDS driver and MySQL driver work fine in isql. For example, the following works without any problem:
isql -v MySQL root mypass
|
This is with a clean install of CentOS 7 Google Compute Engine, as follows:
sudo yum install unixODBC
|
|
|
# MariaDB 10.1 CentOS repository
|
sudo tee /etc/yum.repos.d/MariaDB.repo > /dev/null <<EOF

baseurl = http://yum.mariadb.org/10.1/centos7-amd64

gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
|
gpgcheck=1
|

sudo yum install MariaDB-connect-engine
