Hi, > Unable to run winecfg after a big update of the Arch linux using pacman > -Syu. Wine64 is (currently) broken with gcc-4.8.0; http://bugs.winehq.org/show_bug.cgi?id=33307 That being said, you have a few options. a). use a 32bit wine prefix, instead of default 64bit (look at wine archwiki on how to do this) b). compile wine with gcc -O1 optimization level (instead of -O2) c). compile wine with gcc-4.7.x instead of gcc-4.8.0 I also emailed the Archlinux Wine package Maintainer, and let him know about the breakage on x86_64 with -O2 optimization level. (I never heard back from him). cheerz jordan
