uninitialized value output when calling a product with the count algebra (e.g. alg_count*alg_buyer)

[kmaibach]

The call

gapc -p "alg_count*alg_buyer" elmamun.gap
make -f out.mf
./out 1+2*3*4+5

results in the following output: ( 14 , 2147483647 ) with the second value being some uninitialized value.
I tested this with other grammars and algebras as well, always reproducing the phenomenon.
Only works when calling the count algebra first, thus violating Bellman's Principle.

The preferred output of such a product should instead be an empty set.
