--- Comment #20 from Marcus Meissner marcus@jet.franken.de 2013-03-21 11:28:27 CDT --- the build script referenced does not match the gcc commandline posted.
e.g. it does not contain portions of this: make CFLAGS+="-mincoming-stack-boundary=2" CXXFLAGS+="-mincoming-stack-boundary=2"
Btw, if you remove the CFLAGS+= and CXXFLAGS+= adjustments from here (and move them up where you edit CFLAGS already), you probably also fix the fortify_source reenablement
