Follow-up Comment #2, bug #22818 (project relax): The problem is a number of memory leaks. Parts of the GUI are not being properly destroyed. This can be seen in the Windows Task Manager. In the processor tab, use 'View->Select columns' to add the 'Handles' and 'USER Objects'. Then run the test suite. The failure occurs once the 'USER Objects' count for the process reaches 10,000, the maximum limit in MS Windows. This is why the execution of the failing User_functions GUI tests by themselves does not trigger the bug. _______________________________________________________ Reply to this item at: <http://gna.org/bugs/?22818> _______________________________________________ Message sent via/by Gna! http://gna.org/
