I've seen it happen with user-compiled programs that use the GLUT
(or competing) library to open an X window with an OpenGL rendering
context. Unless linking to some library in /usr/pkg/lib/* or
/usr/X11R6/lib/* runs setuid binaries, these should not be
Also, why would the problem be intermittant, if it were setuid
related? Re-running the program often succeeds (no recompile,
no change of user id, etc.).
While I certainly could be ignorant of something that would make
this an issue, it doesn't make sense to me. Not for the problem
that I've seen.
