[PATCH] PR67518 and PR53852 -- add testcase.

[Andre Vehreschild]

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
