Description
Hello,
unfortunately I missed a bug in Ring::hasIntegerCoefficientRing(); here is the failing example:
LIB("ring.lib");
ring rng = (integer,7),x,dp;
hasIntegerCoefficientRing( rng ); //1 , wrong!
a bugfix is provided in the request
https://github.com/Singular/Sources/pull/567
, but the request was closed...
Note: See

fixed: hasIntegerCoefficientRing -> hasRingCoefficientRing (handles the general case, simpler implementation)
