Comment 28 for bug 1286343

Description of problem:
I'm trying to rebuild mrpt in f20 and f21, and it looks like arm gcc is hitting an error that i686 and x86_64 versions aren't. You can view the build logs at
http://koji.fedoraproject.org/koji/taskinfo?taskID=5928632

The i686 and x86_64 builds finish without issue, but the arm version segfaults consistently at the same point:
