I patched the functions <code data-start="217" data-end="243">Ip::Address::getAddrInfo</code>, <code data-start="245" data-end="268">Ip::Address::FreeAddr</code>, and <code data-start="274" data-end="297">Ip::Address::InitAddr</code> to get Squid working. I’m attaching the modified <code data-start="349" data-end="361" data-is-only-node="">Address.cc</code> that makes it run, but there may be something upstream that forced me to change the code (most likely a <code data-start="466" data-end="474">malloc</code>-related issue). <pre class="moz-signature" cols="72">-- David Touzeau - Artica Tech France Development team, level 3 support ---------------------------------- P: +33 6 58 44 69 46 www: <a class="moz-txt-link-freetext" href="https://wiki.articatech.com">https://wiki.articatech.com</a> www: <a class="moz-txt-link-freetext" href="http://articatech.net">http://articatech.net</a> </pre> </body> </html>
