Description
We have the following:
sage: SymmetricFunctions(FractionField(QQ['q','t'])) Symmetric Functions over Fraction Field of Multivariate Polynomial Ring in q, t over Rational Field sage: SymmetricFunctions(FractionField(ZZ['q'])) Symmetric Functions over Fraction Field of Univariate Polynomial Ring in q over Integer Ring sage: SymmetricFunctions(FractionField(ZZ['q','t'])) Segmentation fault (core dumped)
However, the last one works with Sage 7.3.

Works for me on Sage 7.4.rc1:
sage: SymmetricFunctions(FractionField(QQ['q','t'])) Symmetric Functions over Fraction Field of Multivariate Polynomial Ring in q, t over Rational Field sage: SymmetricFunctions(FractionField(ZZ['q'])) Symmetric Functions over Fraction Field of Univariate Polynomial Ring in q over Integer Ring sage: SymmetricFunctions(FractionField(ZZ['q','t'])) Symmetric Functions over Fraction Field of Multivariate Polynomial Ring in q, t over Integer Ring

That's good to know but slightly unsettling at the same time. I forced a rebuild of symmetrica once I saw this, but I'm now convinced that is not the problem. Maybe it's something with the compiler? I used gcc 5.4.0 to build Sage. Although I guess we should wait to try and diagnose this further once 7.5.beta0
comes out, which should have Singular 4.

Hmm...this now is working for me now that I bumped to 7.4.rc2. I might have just done something to mess up my install when testing stuff... So perhaps we should just close this as invalid.

I don't think this is caused by #12439 as the trace goes through libsingular.
