Hi

finally I have managed to do a small test case that recreates the memory problem I have had for a long time. 
I have attached the dump I get so you can see the result of my execution.

One have to run the test case for some minutes until it breaks.

I have no idea of why it fails after some iteration.

The code in the IALIZER class is taken from eiffelroom (might be some minor changes since I took it some years ago)

Regards

Anders
