--- Comment #4 from Pierre Ossman <ossman at cendio dot se> --- The error didn't indicate anything in our code, so I assumed this was entirely a standard library issue. The file in question is this one: https://github.com/TigerVNC/tigervnc/blob/master/vncviewer/GestureHandler.cxx I'll try to provide a preprocessed file as well.
