There’s a newer gcc5 available as of today—it’s version 5.2.0-2.  I’m not sure whether it will help with your issue, but it may be worth a try.

I found a post ( http://www.spinics.net/lists/gcchelp/msg44306.html <http://www.spinics.net/lists/gcchelp/msg44306.html> ) which suggests that this may not necessarily be specific to our gcj build.
