--- Comment #56 from Roderick Colenbrander thunderbird2k@gmx.net 2008-06-26 15:08:25 --- Wine is doing some evil memory stuff. In short at wine startup we reserve all virtual memory. Dlls and apps need to be loaded in specific parts. Likely there isn't enough virtual memory left for ATI's driver. Alexandre suggested that we might need to do very evil stuff (e.g. override mmap calls made by the driver) in order to fix it. I think a fix is a long time away, so for now revert that patch as I don't think it will be reverted. Note that it might not work for others at all.
