mariadb odbc throws invalid pointer error

I have MariaDB installed (as part of Fedora installation) on Fedora 21. ODBC is also installed. BUT, when I go to test the ODBC configuration (or when Asterisk attempts to use ODBC) I get an error in free():invalid pointer.

odbcinst.ini

 [MySQL]
 Description=ODBC for MySQL
 Driver=/usr/lib64/libmyodbc5.so
 Setup=/usr/lib64/libodbcmyS.so
 FileUsage=1
 UsageCount=2

odbc.ini

 [asterisk]
 Description=MySQL connection to 'asterisk' database
 Driver=MySQL
 Database=asteriskdb
 Server=localhost
 UserName=<theusername>
 Password=<thepassword>
 Port=3306
 Socket=/var/lib/mysql/mysql.sock

Connecting to the database using mysql works perfectly fine using these credentials. But doing:

 echo "select 1"|isql -v asterisk theusername thepassword

results in this:

*** Error in `isql': free(): invalid pointer: 0x00000000011c4e58 ***

I can provide the rest of the core dump if it will help anyone.

Any suggestions for what is causing this and how to prevent it? I need ODBC working.

Solution

I had the same problem on my F21 86_64.

The resolution for me was to install a newer version (logged in as root):

1 remove actual odbc-version (5.2.2 if I remember well)

yum remove mysql-connector-odbc

2 Searching the newest version of mysql-connector-odbc-5.3.4-1.x86_64.rpm) at: http://dev.mysql.com/get/Downloads/Connector-ODBC/5.3/mysql-connector-odbc-5.3.4-1.x86_64.rpm (you need to subscribe)

yum localinstall --nogpgcheck mysql-connector-odbc-5.3.4-1.x86_64.rpm

3 symbolic link creation because unixODBC points still to /usr/lib64/libmyodbc5.so instead of /usr/lib64/libmyodbc5w.so

ln -s /usr/lib64/libmyodbc5w.so  /usr/lib64/libmyodbc5.so

4 if needed don't forget to modify (in ~/.odbc.ini)

.....
Driver64=/usr/lib64/libmyodbc5w.so
