+Subject: [PATCH] libstdc++: no implicit conversion from tuple created with std::tie to an std::pair in restricted cookie manager.
+
+Fix compilation error:
+    ../../services/network/restricted_cookie_manager.cc:164:30: error: no match for ‘operator[]’ (operand types are ‘network::CookieAccessesByURLAndSite’ {aka ‘std::map<std::pair<GURL, net::SiteForCookies>, std::unique_ptr<std::set<net::CookieWithAccessResult, network::CookieWithAccessResultComparer> > >’} and ‘std::tuple<const GURL&, const net::SiteForCookies&>’)
+
+There is no conversion from tuple to pair.
+
