Hello,
I'm using the latest released comtypes version (0.6.1). I have a long
running python process that creates and releases a com object also
written in python. I noticed that this causes a memory leak. This
does not occur if I perform the same operations on a com object
written in C++.
Below is code for the python com server (inproc) and also the test
app. To reproduce:
1. Open task manager
2. python testcomsrver.py -regserver
3. python testcom.py
4. Notice process continues to grow in size...
I'm using ActiveState Python v2.5.4 on 32bit Win7.
