eeek, append 1 on the right place as otherwise we didn't fix the problem

      char *newstr;

         at the end of this function outside the while() loop */

      allocsize = (appendlen + stringlen)*2 + 1;

      newstr=realloc(target, allocsize);

      allocsize = (appendlen + stringlen)*2;

      newstr=realloc(target, allocsize + 1);

      if(NULL ==newstr) {

        return NULL;
