Problem description

The package does not work without feature :colored-poly-use-grobner. The problem is within the file colored-poly.lisp. With this switch, colored-poly.lisp uses itself to compute Groebner bases. The problem is localized to code affected by the switch.

To reproduce the behavior, one should:

• Comment out the (pushnew :colored-poly-use-grobner *features*) forms and load the package.
• Load the system using (asdf:operate 'asdf:load-op 'cgb)
• Switch package: (in-package :cgb-lisp)
• Run all built-in examples: (all-examples)

The package will fail in string-grobner-system.
