https://gcc.gnu.org/bugzilla/attachment.cgi?id=30285 still produces an ICE for
me:

  I have tried this with:
   - My system GCC (g++, version 4.9.1)
   - A native build of GCC (${GCC_TRUNK}/bin/g++, revision r213234)

  ${GCC_TRUNK}/bin/g++ is a native build of GCC, with the following specified
  to the configure script:
  ./configure --prefix=${GCC_TRUNK} \
    --enable-languages=c,c++,fortran --disable-sjlj-exceptions
  And make invoked as: make CXXFLAGS="-g3 -O0" -j9
