    _______________________________________________________

Details:

I have encountered a segmentation fault in octave 5.1 when utilizing a
constant defined in a classdef property.  

Constants are defined in an .m file on the path like so:

_testCrashConstants.m_

classdef testCrashConstants
    properties( Constant = true )

        FOO = 2;
        BAR = 4;
        FOOBAR = testCrashConstants.FOO * testCrashConstants.BAR;
    end
end


The crash can then be triggered by accessing *any* variable defined in the
file.


$>octave-cli
octave:1> testCrashConstants.FOO
Segmentation fault (core dumped)

$>octave-cli
octave:1> testCrashConstants.BAR
Segmentation fault (core dumped)

$>octave-cli
octave:1> testCrashConstants.FOOBAR
Segmentation fault (core dumped)


Commenting out the line 6 FOOBAR definition makes it such that the *FOO* and
*BAR* can be accessed normally, so I would guess it has to do with having a
derived constant in the file.  That said, the same approach runs in MATLAB
without issue, so I believe this is valid syntax.  If not supported by octave,
I would expect an error message rather than a crash.

Below is a full stacktrace:
