I have just seen a related commit in mesa: http://cgit.freedesktop.org/mesa/mesa/commit/?id=f8d81c31cee30821da3aab331a57f484f6a07a5d
and the related bug entry: https://bugs.freedesktop.org/show_bug.cgi?id=27962
So it looks like it is a bug in mesa, not in freeglut.
Unfortunately, that commit cause KWin to segfaults when OpenGL desktop effects are enabled (I have reported that new bug at freedesktop.org).
