I pushed a followup change to make sure the new test is skipped if Octave is built without GLPK:

I made two small changes to your patch:

1) We like to start the line with any conjuction operator like "&&" or "||".

2) We prefer double quotes to single quotes unless there is a specific reason to require the single quote behavior.

I applied it here (http://hg.savannah.gnu.org/hgweb/octave/rev/185038fe7a16).  Thanks, and I'm going to close the report.

Found it. The problem is in the 'status' output of glpk, the meaning of which has changed since changeset 54e251e699bb. I am preparing a patch.

Confirmed that the attached example works in 3.6.4 and generates an error in the development version.
