I guess I need to investigate these failures. A bit weird why it crashes with some NULL-offset'd pointer, I assume. Testbot says some of them are pre-existing (WoW results): https://testbot.winehq.org/JobDetails.pl?Key=125408
Meanwhile a patch without the winex11.drv changes seems to not introduce them at all: https://testbot.winehq.org/JobDetails.pl?Key=125413
Not sure if just (bad) luck yet�
