There's a workaround in the 1.7 release code for an old getaddrinfo  
bug in glibc; the workaround introduces a memory leak.  Greg put a fix  
in back in August to disable the workaround if the glibc version is  
2.4 or later, since the bug was fixed in 2.3.4.  See http://krbdev.mit.edu/rt/Ticket/Display.html?id=6534 
  and some of the comments in src/util/support/fake-addrinfo.c for  
details.  I don't think it's been added to the 1.7 branch yet, so it  
wouldn't have been in the snapshot you got.

You can get a link to the patch from the RT page, or you can try a  
snapshot from the main development trunk ("krb5-current"), if you like.
