However, I also found one new error:

Can you check if these problems are still there with the Singular spkg
posted on #14333?

I compiled stand-alone Singular 3.1.6. It seems to work with at least 4 polynomial that didn't work with Singular 3.1.5.

As to #14333, I was not able to install singular-3-1-6.p0.spkg. What I got was

### Singular spkg-install: build_libfac ###

Error building libfac.

(Type Array<int> should have friend function to get cout<< working if I read this correctly.)
