Result: Unity crashes with Fatal Error.
Reproducible with: 2017.1.4f1, 2017.2.3p1, 2017.4.4f1, 2018.1.3f1, 2018.2.0b6

For me it happened while recompiling scripts after having just saved a script in Visual Studio and alt-tabbing back to Unity...during my session I had made frequent tests in Play Mode (clicking the Play button a lot)...after about 30 or so minutes...the issue occurred.
