Comment (by scanty):
Well, it wasn't the realloc(). According to gdb, the problem lies in
blit_windowed_dirty_mmx, which for some reason is crashing, but works fine
in doublesize mode (just a different function). I don't know how many ASM
nuts there are out there, but maybe I'm doing something wrong with respect
to how Haiku is using registers -- I have no idea. I can't get anything
meaniningful out of gdb, or the graphical debugger, which doesn't seem to
want to touch my code with a ten foot pole. I wrote these blitters a few
years ago, and they have worked fine in Haiku up until recently. If I can
pin down the hrev where things go south, maybe that would be helpful. I
tried a straight memcpy() instead, and even that is crashing, so I don't
really know exactly what the problem could be. Whoever can fix it gets a
free beer. Thanks guys, keep up the hard work.
