getaddrinfo memory leak?

Could someone with gcc and valgrind try to reproduce this leak?

I see getaddrinfo leaking on every call. The exact same program *isn't* seeming to leak on Ubuntu. Theories appreciated.

Re: getaddrinfo memory leak?

These pipes are sealed tight:

$ alias vgfull
alias vgfull='valgrind --leak-check=full --show-reachable=yes'
$ vgfull ./leak
==27665== Memcheck, a memory error detector
==27665== Copyright (C) 2002-2010, and GNU GPL'd, by Julian Seward et al.
==27665== Using Valgrind-3.6.0 and LibVEX; rerun with -h for copyright info

==27665== 
==27665== For counts of detected and suppressed errors, rerun with: -v

edit: in case it's relevant, i'm using the testing toolchain (gcc 4.5.2). valgrind is plain -- version 3.6.0 out of extra.

Re: getaddrinfo memory leak?

Thank you for testing that. Maybe I have something misconfigured w.r.t. nslcd.

Here's my valgrind output: http://pastebin.com/j7SLaiJ5
