Re: [Bug-gsl] GSL 2.3 built with Intel 17.0.0 does not pass linalg test suite

[Stewart, Adam James]

I was just able to successfully pass `make check` with GCC 6.1.0, so I think 
the problem is either transient or restricted to the Intel build. Note that I 
was using `make -j16 check` for both tests.

Hi,

I'm trying to run `make check` on GSL 2.3 built with Intel 17.0.0  on CentOS 
6.7 and am seeing the following test-suite.log:
