Issue DM-1725: stack build fails on gcc 4.8 with opt=3
The stack fails to build with gcc 4.8, with a test failure in meas_base (though a similar problem on the HSC fork suggests the problem is actually in afw). [~darko] reports that on OpenSuse 13.1, the failure goes away when compiling with opt=1 instead of the default opt=3, indicating that the problem is overly aggressive optimization. This, and the fact that a traceback of the HSC-side failure implicates MaskedImage::getXY0, leads me to guess that something is going wrong with the alignment of the Eigen data members in afw::geom::Point. Until that theory is disproven, this probably belongs in my court, though I'd be happy to let someone steal it from me if they're interested in working on it.
