Can somebody try that to see if it fixes the problem?
Actually, it doesn't fix it. And I've backed out that patch. Stephen uploaded another test app which shows that even with srcX/Y as 0 and a negative dstX/Y parameter can still crash the server. It looks like a bug in the way fb uses deltas whereas I've tested the original cfb code and it works fine.
