Yes, most likely.

Hi Greg,

Yes, it is undoubtedly something to do with shared memory. I wonder if
there are two things you could do for us. First, if you have more than
one Dec Alpha, try running the program on one and bringing up the display
on another and see if it works. Also, try running it on an Alpha and
bringing up the display on a Sun or HP or anything besides the Alpha and
see if it works. Finally could you mail us the results of these tests as
well as the output of "xdpyinfo" for the Dec Alpha X server. It may take
a while to fix whatever is wrong with the Alpha version since we don't
have any of those machines here.

Thanks,
Daeron
