### Description

some overflow bugs as in www.singular.uni-kl.de:8002/trac/ticket/631 seems fixed now.(which commit?)

Here is one more:

ring rng = 0,(x,y),dp; short = 0; poly h = x^2147483647; ideal I = h; ring G = 0,(a,b),dp; short = 0; ideal phi = a,b; map m = rng,a^3,b; m(I); // =a^2147483645*b , wrong!! quit;

so it is not the end of the story. Also the computation takes about a minute to finish.
