   Thanks for the quick reply. Unfortunately it doesn't
work.

   For example the following program will produce a
segmentation fault:

    int main()
    {
       char *c;
       c = NULL;
       printf("%d",strlen(c));

    } 

   I expect the output to be zero, but it produces a
segmentation fault everytime I ran it.

regards,
ludwig
