Memory Leak in GDO

[Rene Cornils]

Hi there,

I encountered a significant memory leak when using GDO (base 1.0.1). Even
for very simple programs, both client and server consume more and more
memory on every transaction (the server side seems to be more affected by
this problem).
Below you can find some simple source code for demonstration.

Is this a bug or am I doing something wrong? Any help is highly
appreciated.

Thanks in advance
Rene
