Hello, since I changed to version 4.3.2 it seems that calling associated_primes() on an ideal of a polynomial ring that has term order 'invlex' is broken.
Example: sage: R.<x,y>=PolynomialRing(QQ,2,order='invlex') sage: R.ideal(x).associated_primes() ? // Not implemented for this ordering, please change to global ordering. ? leaving primdec.lib::primdecSY Traceback (click to the left of this block for traceback) ... RuntimeError It used to work fine with prior versions. Is this an intended change? Also, it seems that this leaves the spawned singular process in a broken state as all subsequent ideal operations (e.g. simple membership tests) will fail until the worksheet is restarted.
