--- Comment #6 from David L. equinox-freedesktopbugs@diac24.net 2011-06-24 22:16:49 PDT --- Created an attachment (id=48391) --> (https://bugs.freedesktop.org/attachment.cgi?id=48391) debug output
debug output attached, started on the game screen before the one using the failing shader. i can't quite make out what source belongs to what... look for "#2518" to find the error.
(no idea if the SEGV at the end is related)
