Hi YaST hackers, maybe some of you already see lot of failures in factory YaST. One of goodly hidden problem is mixture of code compiled with c++1x and c++98. This is exactly what cause segfault in gtk sw_single. for explanation see comment from michael matz - https://bugzilla.novell.com/show_bug.cgi?id=767666#c11 Core is compiled with c++1x ( due to libzypp I expect ). So other parts that use core should be also compiled with this flag.
