AutoStrip is a Wardrobe feature that, when turned on, removes all items contained in a folder as soon as a single item in that folder is removed. Note that you'll need to activate it per item (edit item > Dressing > AutoStrip).
When you're wearing items from many folders and/or your folders have long names, the AutoStrip script can run out of memory, causing the stack heap collision. If you don't actually need AutoStrip, you can just turn it off to prevent the error from happening in the future. To do so, make sure you're wearing your Wardrobe HUD. Then, on your Wardrobe web page, go to Preferences > Dressing, then click "Turn off AutoStrip." After that, reset the HUD (click the Menu button on the 1o'clock position, the click Setup > Reset HUD).
