If USE_SYTEM_MALLOC is defined then, as its name suggests, the system malloc implementation will be used. I believe that the Qt port always uses the system allocator as there is no portable method of restricting the scope of global operator new to a single library, and they did not wish WebKit's custom allocator to interfere with Qt client applications. - Mark _______________________________________________ webkit-dev mailing list [email protected] http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
