Unless I'm mistaken, the polynomials are at the end. I guess that the heuristics used by Singular for sparse multivariate factorization did not succeed for this polynomial (this pair is slightly more complicated than the previous pairs), and reverted to dense factorization (probably Hensel lift algorithm), which requires much more ressources (I have checked with giac and aborted after half an hour and more than 8G of RAM required).
