[Bug 1041084] Re: memory leak while assigning boost::python attributes
@Bruno: unable to reproduce #11, tried this with Woo:
from woo.dem import *
e=FlowAnalysis()
import sys
for k in range(10000):
sys.stderr.write('.')
e.flags=range(0,1000000)
(FlowAnalysis.flags is declared as vector<int>). Memory usage is sitting
at 0.6% with no change at all.

Title:
memory leak while assigning boost::python attributes
Status in Yet Another Dynamic Engine:
New
Bug description:
I detected a memory leak in O.bodies.erase, when facets were erased (spheres are erased without memory leak!).
In the attachment you will find two files, where you can reproduce the bug.
1. Open a terminal with three tabs.
2. Run top or htop in the first terminal tab
3. In the second terminal tab run yade input file "memoryleak-erase-facets.py"
4. Get the pid from first terminal tab (example 31667) and edit "get-memory-info.py"
5. Run "python get-memory-info.py" in the third terminal tab and wait (ca. 5 min) to the end of the calculation.
You will get an output file called "fig-memoryleak-erase-facets.png",
where you can see the effect of the memoryleak.
