There is definitely a problem here. I see the crash also.

What happens is the added table appears to be already used in the selected workarea when you enter the dbc_AfterAddTable proc. The crash occurs if you reference that workarea. You can avoid the crash by adding a USE command at the top of the procedure to close the added table. Your code still doesn't work, though, because of a couple of other problems. For one (as I think someone else already pointed out), you can't add a table that is in use, so you have to add a USE between your CREATE and ADD TABLE commands.

More fundamentally, the ADD TABLE within the dbc_AfterAddTable will cause a recursion. This manifests itself as an "Alias name is already in use" error. If that didn't happen, I think you would hit the program stack limit of 128. I can't really tell what you are trying to accomplish, but I did report the crash as a bug. I'm not sure if the added table should be automatically opened, but either way it should not crash.

Thanks for bringing this to our attention!
