Comment(by zimmerma):
Replying to [comment:1 mpatel]:
> Possibly naive question: Is this a problem in the Maxima wrapper or in
Maxima itself?
it seems to be a problem in the main Maxima {{{to_poly_solve}}} function.
With the option
{{{use_grobner=true}}} it returns (but never gets a chance to get there in
the try ... except).
> Out of curiosity: Does this system have a special provenance?
yes, it comes from Coppersmith's algorithm to find small roots of a
polynomial system, which was itself used by a master student (Thomas
Prest) in the context of polynomial selection for the
Number Field Sieve with two non-linear polynomials.
