Causes of issue are:
- Compilation option: we compile with RPM default + some extra. Maybe removing extras would solve the issue ?
- versions of the lib used in dependency

We have tried to reproduce this, including on a real Red Hat Enterprise Linux, but no success - there was no memory leak.
I can't figure out the cause of this without seeing it in action. Since we have since changed the backend code from hdb to mdb (in 4.1), it is highly likely this no longer happens - but not certain.
Since there are no actions possible on this for now, and we have had no further reports since almost a year, I'm going to close this as it's not reproducable. I don't doubt the bug exists, I just can't see a way forward without a machine to reproduce it on, and the original reporter for this problem can't give us access to the machine where it used to happen (and it no longer happens) for us to investigate.
If ever this bug reappears, please reopen this ticket and we will do our best to investigate.
