Hi Paul,
I fell for the same issue. You need a more recent isl library then
0.14.2. I installed 0.12.something when I started gfortran hacking and
didn't upgrade since.
You can get the ISL lib from:
ftp://gcc.gnu.org/pub/gcc/infrastructure/
or from your distribution (Fedora 21 is shipping 0.14.3, which is
sufficient to run the test.)
Regards,
Andre
