[New-bugs-announce] [issue36756] createcommand memory leak

[Wolfram Kraus]

New submission from Wolfram Kraus <wolfram.kraus at hagen-partner.de>:

When using tk.createcommand you get a memory leak when you don't explicitly call tk.deletecommand to remove this command.
See attached file: __del__ never get's called due to the memory leak and because of that calling tk.deletecommand inside __del__ has no effect. If you remove the tk.createcommand everything works fine.
