Summary: i915 20050517 seg fault in sdrawXORline4
Product: DRI
Version: DRI CVS
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P3
Component: DDX drivers
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
I downloaded latest i915 snapshot "i915-20050517-linux.i386.tar.bz2"
and ran blender 3.26.
Every time I pressed 'b' (boundary select command) segmentation fault is
occured.
When I use dri driver included in xorg-x11 6.8.2-r1, I havn't saw segmentation
fault.
Environment:
distribution:gentoo
