Description Paulo César Pereira de Andrade 2008-04-30 13:41:45 UTC 
Created attachment 16267 [details] [review]
0001-Fix-an-off-by-one-read-error-in-drmSIGIOHandler.patch

It could "smash" some drm related variables on the stack
as it is "aligned".

  I believe the problem also exists in git master.

  If I recall correctly, I added this patch long ago after working
on testing (or trying to...) the X Server with valgrind. But forgot
to submit to freedesktop.
