Subject: MListbox memory leaks
Download (untitled) / with headers
text/plain 616b
This is happening with Tk::MListbox 1.11. I tested it on Fedora Core 2 and Windows 2000. I am observing memory leak when using MListbox. The leak happens both when deleting/re-inserting the list and when sorting. I monitored the memory leak by using "top" in Linux and using the task manager in Win2k. The memory seems to go up by the same amount every time. I could not find the source of this problem. The problem may lie in Tk::Listbox itself and not MListbox, I can't say for sure. The attached script demonstrates the problem. Everytime the button is clicked or the column is sorted, the script leaks memory.
