Comment 2 David Howells 2015-05-14 08:40:21 UTC 
I've raised a gcc bugzilla for it:

Comment 3 Jan Kurik 2015-07-15 14:11:21 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle.
Changing version to '23'.

(As we did not run this process for some time, it could affect also pre-Fedora 23 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.)
