Bug fix.

Description of problem:

The ODBC version of the mysql connector is completely broken.

This has already been reported to Oracle:

http://bugs.mysql.com/bug.php?id=75196

Typically, it takes them about a year, to fix things like this.

Attaching a patch that fixes the bug to me.

Wow, thank you very much, Sam!

Comment 4 Sam Varshavchik 2015-06-09 21:04:32 UTC
The patch is wrong.

It's not just the null check, free() must be used instead of x_free(). The pointer is allocated with malloc(), and must be disposed of with free(), not x_free(), as my patch does.
