Description:

Hi,

I have had an ongoing memory leak with Informix for a while now and haven't had another database to test with so I can send in evidence for investigation.

I have written a small script that created a database connection using Pear::DB and loads creates a loop to load an array of objects.

To run the command:
php testMemoryLeak.php ORACLE
or 
php testMemoryLeak.php INFORMIX


If you run this code (see below) and then issue the command 
ps -ax -o '%mem cmd' | grep 'testMemoryLeakPEAR.php' | grep -v 'grep'

On the informix run, the memory goes up and up (try running the program and see after a couple of minutes), but with the oracle run, no memory leak.

This should provide enough clues to maybe find the leak and plug it for informix.  Please help, this is starting to be a very big problem for my project.

Thanks in advance 
Michael

Reproduce code:
---------------
https://student.transport.nsw.gov.au/testMemoryLeakPEAR.txt

Expected result:
----------------
The program should be downloaded and set up to use with both a table in oracle and informix

The ps I explained should be run while the php script is running.  

Informix: memory starts at 1.5 and starts going up every minute or so
Oracle: stable.

I think the problem is in the free() class.
