thanks. Do you plan a new release soon with that patch and that of #424, so that we can upgrade the Singular version in Sage?

here is another test case (with the version of Singular shipped with Sage 5.0, i.e., 3-1-3-3.p6):
singular: ring r=2,(x,y),dp; ring r=2,(x,y),dp; singular: poly p=x^6 + y^5 + y^4 + y*x^3; poly p=x^6 + y^5 + y^4 + y*x^3; singular: factorize(p); ... Segment fault/Bus error occurred at 44b84d01 because of 10287 (r:1337846517)

This one's fixed as well in the most current version.
