Re: gethostbyname_r leaks memory

[Wolfram Gloger]

Hi,

I can easily reproduce this problem.

I have some evidence that the leak is caused by the following:

            if (EXT(statp).nsaddrs[n] == NULL)
                 EXT(statp).nsaddrs[n] =
                            malloc(sizeof (struct sockaddr_in6));

from resolv/res_send.c near line 440, which is apparantly producing
lots of small chunks which in the multi-thread case are never freed.
Perhaps someone who understands the resolver logic better can fix it
straight away?  I might take a look too but it's probably going to
take some time..

Wolfram.
