We can reproduce this problem with Linux guests as well (running 4.15 Ubuntu Xenial and 4.14 Android kernels). Mac models with integrated GPU seem to be more affected according to our testing, and the crash does not always occur, needs multiple tries to be triggered. We would be happy to assist in debugging, once you have a patch that can generate more detailed logs.
