Bug#273051: Memory leak in libc getpwuid() and getgrouplist()

[Chaskiel M Grundman <cg2v@andrew.cmu.edu>]

Package: libc6
Version: 2.7-10
Followup-For: Bug #273051

I am seeing this behavior on amd64, both with 2.3.6.ds1-13etch5 and 2.7-10

I think this is a __libc_freeres problem, since if I run valgrind with 
--run-libc-freeres=no, the relevant blocks are reported as being still 
reachable (in fact, no leaks are reported at all, all allocated blocks are 
reported as still reachable.)

This problem appears to have been reported upstream, but was 
essentially ignored 
(http://sourceware.org/bugzilla/show_bug.cgi?id=2314. a test case in 
source form _was_ provided, but probably not enough details if 
passwd: compat is a requirement for reproducing it)
