Actually this does not seem to be the case. I still see the error with the
following GCC build (on Ubuntu 16.10):
Target: x86_64-linux-gnu
Configured with: /home/janus/gcc/trunk/configure --program-suffix=-7
--build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu
--prefix=/usr --libdir=/usr/lib --libexecdir=/usr/lib
--enable-languages=c,c++,fortran --disable-multilib --with-arch=haswell
Thread model: posix
gcc version 7.0.1 20170212 (experimental) [trunk revision 245376] (GCC)
Since no one can reproduce it, maybe it is Haswell-specific? I'll check if
removing "--with-arch=haswell" helps ...
