One more thing that can commonly go wrong: you aren't erasing items in a vector while looping over the vector?
As I said in my previous post memory should not be freed in the undo layer. It should stay separate while I create new layers.
Layer holds a pointer and memory is freed for all layers in the vector when the tool exists.
I'm erasing in the vector by doing:
Code:
layers.erase(layers.begin()+ index);
I understand it is hard for you to understand exactly what is going on but it is not easy to post code examples... I might be able to get somthing together though.
