Comment 5 for bug 1621188

Orson,

Yes it does, but I have that fix in and it still crashes. So the program still has one or more bugs re: PNS.

In the latest crash there was involvement with the undo buffer. I was running with no debugger, single_top. I went to route a new segment, rounding off a corner, and after entering routing mode, there was ghosting from tracks that were not really there, but that were in the undo buffer. These appeared just as I entered routing mode, and they were concurrently visible with the *current* segments. After moving the mouse just a little, then segfault.
