Details:

When I compile the new release candidate 4.0.1-rc1  of Octave on my Ubuntu
14.04 machine, I get two failing tests from __osmesa_print__.cc-tst . I am not
quite sure if this is a dublicate of bug #44338 , that's why I opened a new
issue.

Here is what I did in more detail:

cd /opt/octave-4.0.1-rc1/
export JAVA_HOME=/usr/lib/jvm/default-java
./configure
make
make check


The result of make check is:
PASS   12930
FAIL       2
XFAIL     14
SKIPPED   62

And the details in fntests.log are:

>>>>> processing

***** testif HAVE_OSMESA, HAVE_GL2PS_H
 if (isunix ())
   h = figure ("visible", "off");
   fn = tempname ();
   sombrero ();
   __osmesa_print__ (h, fn, "svg");
   assert (stat (fn).size, 2692270, -0.1);
   unlink (fn);
   img = __osmesa_print__ (h);
   assert (size (img), [get(h, "position")([4, 3]), 3])
   ## Use pixel sum per RGB channel as fingerprint
   img_fp = squeeze (sum (sum (img), 2));
   assert (img_fp, [52942515; 54167797; 56158178], -0.05);
 endif
!!!!! test failed
__osmesa_print__: Depth and stencil doesn't match, are you sure you are using
OSMesa >= 9.0?

some notes:
* I have libosmesa6 installed, in version 10.1.3-0ubuntu0.5 from the Ubuntu
repositories for Ubuntu 14.04.
* when I do "export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libGL.so" and then
"make", then I get the very same failing tests
* I have seen no crashes at all, only failing tests. Doing "test
__osmesa_print__.cc-tst" inside of Octave does not crash either.
* This is a laptop with inbuilt Intel graphics. No NVidea graphics card. No
propietary graphics drivers (as far as I know).

Anything more you need to know?
