patch

I can reproduce this, but it doesn't look like multisampling has much to do
with it, it crashes just as well with multisampling disabled. Does
WINEDEBUG=warn+heap make any difference when you have multisampling disabled?
Do you happen to know if this works on Windows XP? The attached patch avoids
the crash for me, but code like that was removed for bug 7970.
