Details:

Hello,

I am using GNU Octave Versions 3.4.3 and 3.6.0. under Windows 7.
there occurs an error in GNU Octave 3.6.0 with surf()-Funktion and textures.
the simple example code in attachment(zip-file) is tested in matlab 2007a and
GNU Octave 3.4.3 and works fine with this. In Gnu Octave 3.6.0 this example
crashed with error:


error: invalid color specification: texturemap
error: invalid value for color property "facecolor" (value = texturemap)
error: called from:
error:  
C:\USR\Octave\Octave3.6.0_gcc4.6.2\share\octave\3.6.0\m\plot\surface.m at line
159, column 7
error:  
C:\USR\Octave\Octave3.6.0_gcc4.6.2\share\octave\3.6.0\m\plot\surface.m at line
51, column 23
error:   C:\USR\Octave\Octave3.6.0_gcc4.6.2\share\octave\3.6.0\m\plot\surf.m
at line 51, column 9
error:   C:\work\octave\test_surf.m at line 14, column 3
panic: Segmentation violation -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete


to prevent "panic: Segmentation violation...." wrapped a try ....catch around
the surf-function, so Octave 3.6.0 not hangs up!

when you cut out the 'FaceColor','texturemap', then Octave hangs suddenly(with
try ... catch..., and also Octave 3.4.3 crashing under this condition)
with error:

panic: Segmentation violation -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete

For testing purposes in the zip file is also matlabs topo.mat and the
minimized code example wich crashed in Octave 3.6.0.

Hope its helpful report!

Best Regards

 Stephan Gebauer
