GuestProcessImpl.cpp@ 78352

Last change on this file since 78352 was 78234, checked in by vboxsync, 6 years ago
Main/GuestCtrl: Fixed three i_waitForStatusChange() methods that would return VERR_GSTCTL_GUEST_ERROR without setting prcGuest, making the caller use uninitialized stack as status code for the operation. bugref:9320
