This does not mean anything.  These tools simply don't do the
necessary things.  Plus, your program is not freeing the resources
itself.

There is no leak with the services I'm using (only nss_files).  If you
would understand only a tiny little bit of the issue and would read a
bit in the manual you would write

#include <mcheck.h>
int main(int argc, char **argv)
 {
        struct hostent *h;
mtrace();
 
        h = gethostent("host name in here");

endhostent();
 
        return(0);
}


$ MALLOC_TRACE=OUT ./program
$ mtrace program OUT


and you would see what really happens.  And note the endhostent() call
I had to insert to correct your mistakes.

The only one who is agressive is you.  You come in, don't even
understand the problem, and call people stupid.
