Oh i bisected that ine, it takes 200X more time to compile on 32bit :D , actually compile libmesa_gallium i think this is the commit: http://cgit.freedesktop.org/mesa/mesa/commit/?id=d55f77b503ab7b59ecdd8f31c4f7dc498710e75b -- You are receiving this mail because: You are the assignee for the bug. --1409948590.62dCb30.15814 Date: Fri, 5 Sep 2014 20:23:10 +0000 MIME-Version: 1.0 Content-Type: text/html; charset="UTF-8"
