> All the callers of the function prepend_string make a call to prepend_string 
> before checking that zhandle_t *zh is not null. At the top of prepend_string, 
> zh is dereferenced without checking for a null ptr:
> static char* prepend_string(zhandle_t *zh, const char* client_path) {
>     char *ret_str;
>     if (zh->chroot == NULL)
>         return (char *) client_path;
> I propose fixing this by adding the check here in prepend_string:
> static char* prepend_string(zhandle_t *zh, const char* client_path) {
>     char *ret_str;
>     if (zh==NULL || zh->chroot == NULL)
>         return (char *) client_path;
