Comment:
Actually, this problem doesn't look like related to ASLR.
In `PretendoWindow::DrawDirect` line 818 the variable `y` has value `-1`
what makes `blit_windowed_dirty_mmx` attempt to read from an address
before the start of the actual buffer, hence page fault.
I do not know whether it is a Haiku fault or a bug in the application,
because I am not familiar with this part of Haiku and, unfortunately, at
the moment I don't have enough spare time to get familiar.
