Running Xcode 9.4.1 on macOS 10.4.2, when I click on a combo box in a window, in the debugger I get an exception:
[General] The window has been marked as needing another Display Window pass, but it has already had 3 Display Window passes. Future marking as needing Display Window might be ignored.Nothing appears to be complaining about ambiguous constraints, and searching for that message produced no hits.
Anybody have a clue what to look at?
