Sorry forgot to mention, @jwe thanks for the quick fix.

I verified the failing example of the OP is now working properly in Octave 7.

Closing report.

I pushed the following changeset to fix the way we were handling "properties", "methods", "events", and "enumeration" as keywords in the parser:

http://hg.savannah.gnu.org/hgweb/octave/rev/ad1491462d13

This change was made on the default branch so will not appear in a released version of Octave until version 7.

Using the function 'properties' inside a classdef results in a parse error.  The following class cannot be instanciated:

classdef PropFail
   properties
      some_prop
   end

   methods

      function props = failingMethod(instance)

         props = properties(instance);

      end

   end
end

If I try to create an instance, the following happens:

octave> obj = PropFail()
error: parse error near line 10 of file /home/oddan/gitted/source/mrst/mrst-other/ruden-geothermal/PropFail.m

  syntax error

>>>          props = properties(instance);
                              ^

If, on the other hand, the 'properties' function is moved out of the lexical scope of the classdef, it works fine:

classdef PropWorks
   properties
      some_prop
   end

   methods

      function props = failingMethod(instance)

         props = getprops(instance);

      end

   end
end

function p = getprops(instance)
  p = properties(instance);
end

I can create an instance of the latter without problem:

octave> obj = PropWorks()
obj =

  PropWorks object with properties:

      some_prop: [0x0 double]
