This causes any programs using OpenGL in this way to fail. >How-To-Repeat: Try and run any piece of code using the OSMesa libraries. The osdemo.c program provided with Mesa for example: cc -I/usr/X11R6/include osdemo.c -L/usr/X11R6/lib -lGL -lGLU -lglut -lOSMesa ./a.out Illegal instruction (core dumped) According to gdb the error occurs in gl_katmai_transform_points3_3d_raw() and this is where I also see it when running my own code. >Fix: None known. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
