Aborts with GiNaC usually mean an unhandled exception. Catch and print it,
and it may give you a hint about where the problem is.

Introducing noncommutative objects probably exceeds the domain on which
the algorithm used by the linear solver is defined. Manually choosing a
different algorithm (maybe "solve_algo::divfree"?) may fix this. Richy?

Bye,
Christian
