Unfortunately I cannot test the original program I had the problem with, because since the original post (2006) I changed the employer. Now I use Matlab :( -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1524938 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Mark Matusevich mark...@users.sourceforge.net added the comment: It looks like the severity of this problem is underestimated here. A programmer working with a significant amount of data (e.g SciPy user) and uses OOP will face this problem. Most OOP designs result in existence of some loops (e.g. two way connections). Some object in those loops will include huge amount of data which were allocated by a single operation if the program deals with some kind of algorithms (signal processing, image processing or even 3D games). I apologize that my example is artificial. I had a real-life program of 8000 lines which was going into swap for no apparent reason and then crashing. But instead of posting those 8000 lines, I posted a simple example illustrating the problem. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1524938 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
