new greetings from exponent overflow hell

[kroeker@…]

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.

fixed with 0b9aa7febb094f9895da3d802b389bd9560e3c48 PS: a MINIMAL example would be better: see bug_tr696.tst
