What is the purpose of the above line?

I don't see a leak when running it under Linux (after commenting out the line that tries to append NULL to the header list), but it's with an older version of libcurl, so not really a valid test. > BTW, if not complied including zlib and not using CURLOPT_ENCODING, there is > no memory leak problem. > > thank you. -- Michael Wood <[email protected]> ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
