Description:
I upgraded today my system (first time in long time) and then I tried to build calligra 2.8 I was unable to do it as I received the message that can be found in additional info. I started googling and it let me to this gcc bug:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57532

It looks that this bug still remains in the newest package of gcc (GCC) 4.9.0 20140507 (newest as of today)
Please check if it is a case and fix it if possible as it blocks my work
