--- Comment #4 from Zebediah Figura z.figura12@gmail.com --- Sorry, accidentally hit submit.
The application crashes inside of the window procedure for "SimpleGraphic Class" while handling WM_ACTIVATEAPP. It's basically expecting none of the calls in the sys_video_c constructor [1] to trigger WM_ACTIVATEAPP, but Wine does send WM_ACTIVATEAPP while taking focus from the window. I'll have to check to see whether that's correct, but I'm not immediately sure why it wouldn't be.
