Which branch (or target) is affected here? I cannot reproduce it w/ any of
4.9.3, 5.3.0, or 6.0.0 (as of 20151213) for x86_64-pc-linux-gnu.

I can reproduce this one with:
Using built-in specs.
COLLECT_GCC=./xgcc
Target: x86_64-unknown-linux-gnu
Configured with: /home/marek/src/gcc/configure --enable-languages=c,c++
--enable-checking=yes -with-system-zlib --disable-bootstrap --disable-libvtv
--disable-libcilkrts --disable-libitm --disable-libgomp --disable-libcc1
--disable-libstdcxx-pch --disable-libssp --enable-isl
Thread model: posix
gcc version 5.3.1 20160202 (GCC)

But not anymore with 6.

Are gcc 5 and 6 in your setup linked against different versions of ISL? In my
case, it was 0.15 for all installed gcc versions back in December and 0.16, for
all of them as well, as for now.
