Definitely looks like it.  The following program grows in memory usage 
till exhausted.  "saddleback" is just the name of a local machine in the 
dns.

#include <netdb.h>

main ()
{
  struct hostent *h;
  int i = 0;

  while (1) {
    h = gethostbyname("saddleback");
    i++;
    if (i % 100 == 0) sleep (2);
  }
}


Haven't spotted where the leak is yet.
