Hello,
I checked my program with 'mpatrol' (this is tool
similar to purify) and it showed memory leak. All
unfreed allocations were related to gethostbyname_r
function. Actually allocations had always been done by
somewhat function called from gethostbyname_r. You can
see it:

unfreed allocations: 157 (16981 bytes)
    0x08089000 (28 bytes) {malloc:21021:0}

Do you have any ideas? Is it related to
gethostbyname_r or mpatrol. I consultated on mpatrol
site and they suggested it was real gethostbyname_r's
fault. And what are yours suggestions?

Thanks in advance.
