    Description

      1. Create an x86 emulator device.
      2. Run the simple example from QTBUG-70657 and input an emoji character.

      It crashes with SIGILL and the following stack trace:

      I am unsure if this a compilation error or an emulator error or possibly a cross-platform bug that happens when you use color fonts together with the FBO readback workaround.
