Wonderful! Now I know how to used gdb with python. The are results area
posted below. Since I am new at this I could used some help in
interpreting the problem. What I do know is this: my allocation of the
array is good but when freeing the array, a problem arises. The problem
is given below but since I am new as well to C I sure could use some
help.

I appreciate your help so far and could use some more.
