The piglit gl30basic hit this. Cc: "10.2" <<a href="mailto:mesa-stable@lists.freedesktop.org">mesa-stable@lists.freedesktop.org</a>> Reviewed-by: Ian Romanick <<a href="mailto:ian.d.romanick@intel.com">ian.d.romanick@intel.com</a>> It changed a if (n == 1) into a if (_mesa_bitcount(...) > 1) without any regard for n, which might be 0. Should probably be if (n > 0 && ...) or if (n == 1 && ...). Not entirely sure what the logic is there though.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
