Hi, thanks for the report.
I tested with Xorg 7.1.1 only and on Linux only - I will try to find
out what's happening on 7.1.0.

Ouch. Probably I should have better figured out how the IO address is
chosen instead of copying the address that the original VMware PCI
card uses.

Probably the guest driver is passing coordinates that we don't expect
- we don't check that they are in range. Disabling the
#define HW_RECT_ACCEL
#define HW_FILL_ACCEL
near the top of hw/vmware_vga.c should make it safe before it's
properly fixed. I will be offline for the whole week from now :(

Thanks,
