    Description

      I recently updated my operating systems to ubuntu 17.10.

      I have 2 machines running ubuntu 17.10.

      I noticed that qDebug doesn't work anymore.

      I tried to check the check box "run in terminal", but qDebug can't work no matter what. Nothing will be printed.

      I tried printf, which can print in terminal, but won't print in the QtCreator's application output window.

      I suspected this was a regression of qt 5.10,

      but I reverted to qt 5.9.3, the issue still exists.

      looks like ubuntu upgrade broke Qt qdebug.
