Description of problem:
Trying to connect to mysql database via odbc interface in php leads to an error on 64bit systems (seems reliably reproducible on x86_64 and ia64, ppc doesn't exhibit this):

*** glibc detected *** php: double free or corruption (!prev): 0x60000000001dc8a0 ***


Version-Release number of selected component (if applicable):
php-odbc-5.1.6-27.el5_5.3.ia64

How reproducible:
always? on x86_64, ia64

Steps to Reproduce:
1. run the test /CoreOS/mysql-connector-odbc64/Sanity/php-mysql-odbc
  
Actual results:
