The Octave developer for this code made a change based on:

I attached a preliminary patch that avoids using the GL_SELECT mechanism when
we are only looking for axes objects. 

This change prevents the seg. fault.

Do you need more information?

Thanks for looking at this problem.

Ugh, looks like there's some sort of unintended recursion going on here.
I think Anuj might want to take a look at this.

I should have added that the graphics in my system is
Intel HD 6000 in an Intel NUC5i5RYH.

I believe that the seg fault actually occurs in Octave. I could
run a backtrace but, in any case, other Octave developers can do
this quicker. If it is found that there is a problem in the Mesa
code, they will get back to you.

I just thought that it would be good if you had a look.

--- Comment #1 from Brian Paul bri...@vmware.com ---
Can you debug this a bit to see where this is happening and what the texture
target is?

I don't see how this would directly lead to a segfault in Mesa.  After the
error message we select the null_sample_func() function for texture sampling,
which is a no-op.

panic: Segmentation fault -- stopping myself...

This occurs using the latest development version of Octave. I suspect
(strongly) that this originates due to an error in the Octave code
which handles mouse events. But, such a user error should not result
in a seg fault in the user program.
