Summary0020085: Arrays on ds lists leak memory when replaced
DescriptionI have a rather large ds_list on this project that contains arrays representing world geometry. Whenever I take one of these out, edit it, and put it back in the same position on the list, memory is leaked. Big operations like smoothing out normals, which change all arrays in the list, leak huge amounts of memory. Eventually the game crashes.

The only way to not have a memory leak in this case is to use accessors, which I will be using from now on, but still...

To sum up, when you replace an array on a ds list, the stray array that was already there doesn't get deleted and leaks (I'm assuming). Taking a value out and reading from it isn't a problem since it doesn't get duped for that.

I did not test other data structures.
Steps To Reproduce- make a ds list
- make a large array
- add array to list
- write to array, and put it on the same position of the list
- notice memory leak the size of the array

Additionally, setting the local var holding the array reference to 0 afterwards does not solve the problem since that one is correctly cleaned by the engine at the end of the script.

Is it possible for you to attach a sample to your bug report so that we can investigate it?

Can we get a sample project which shows this, please?

I suspect this has been fixed previously as I cannot reproduce it in the current version
