I have met the following Segmentation fault during make check.
  libinterp/dldfcn/__osmesa_print__.cc-tst ....................panic: Segmentation fault -- stopping myself...
octave exited with signal 11

Platform Ubuntu 14.04 LTS 64bit. gcc-4.8.2.

Tatsuro,

The OSMESA facility in Octave is of use only for printing off-screen figures with OpenGL and this happens mostly when Octave creates it's own documentation.  Given that we are still restricted to using gnuplot to create the documentation anyways, and that the documentation is shipped in the distribution tarball so user's don't need to re-generate it, this problem should not be a gating item for the 4.0 release.

I pushed a cset (http://hg.savannah.gnu.org/hgweb/octave/rev/d9f6260cf20a) that disables the __osmesa_print__ tests when not running on a UNIX platform.  There is a bug report on this issue that I am leaving open that will remind us to eventually fix this (https://savannah.gnu.org/bugs/?44338).

Cheers,
Rik
