A bug about layer undo

[puslim]

1. create a layer
2. create a box on the layer
3. delete the layer
4. press undo
5. create new layer
   After those steps , I found the box is changing into the new layer
   I thought there is something wrong of dbLayoutLayers.cc:263(LayoutLayers::do_insert_layer).
   Maybe m_free_indices should find the index and remove it.

You're right. Perfectly reproducible.

I will debug the issue. Thanks for reporting it.

You were right with your analysis. Good catch. The bug must be have been there forever. I wonder how come no one noticed ...

Thanks,

Matthias
