Yeah, that works and is certainly an improvement to building with
gcc-4.8.
I doubt I'll be able to determine myself (in any reasonable time) if
the actual problem is undefined code or a real gcc bug.
Is it OK by you if I clone a gcc-4.9 bug about this now and just
apply the above workaround to libapache2-mod-perl2 ?
