Windows Crash On Mission End With Torque_disable_memory_manager

by Stephane Conde · in Torque Game Engine · 10/26/2006 (5:06 am) · 2 replies

When the TORQUE_DISABLE_MEMORY_MANAGER preprocessor directive is defined, I get a crash on mission end in Windows.

The crash happens everytime when the MissionCleanup group is deleted in the endMission() script function. The crash happens with different objects and in different functions, but always when MissionCleanup is being deleted.

More specifically, the crash seems to always happen when a ShapeBase object inside of the MissionCleanup object is deleted.

What's most bizarre is how specific this bug is. The bug only occurs on Windows when a ShapeBase object is being deleted via the MissionCleanup group when TORQUE_DISABLE_MEMORY_MANAGER is defined. I have tried running the same code with TORQUE_DISABLE_MEMORY_MANAGER defined on my Mac and things work fine. I have also tried running the same code on Windows with TORQUE_DISABLE_MEMORY_MANAGER not defined and things work fine. Lastly, deleting all the ShapeBases manually while in the mission (either through the mission editor or through the console) works fine as well... its just when those ShapeBases are deleted at the end of the mission via MissionCleanup that it crashes.

Would anyone have any ideas as to why this is happening? I know that I can just keep TORQUE_DISABLE_MEMORY_MANAGER undefined, but I am very curious as to why this doesn't work... and a little worried.

If any has any information that might help, it would be greatly appreciated!

Thanks,

Stephane
