Another case is in qt4-x11-free-4.8

The same qt4-x11-free-4.8 compiles fine with oe-core only, so I suspect that one of those extra linaro patches in meta-oe's gcc-4.6 is causing this.

Preprocessed source is here: http://build.shr-project.org/tests/jama/gcc-issue/MD5.o.E

Passing -fno-tree-vectorize can be used as work around again (like with libvpx/libav/mplayer2).
