Comment:

 This also affects Intel 18. I suggest to for now test for all intel
 compilers >= 17.00 and add the upper bound once we find a compiler that
 works again. I would also backport this to the release branch.

 Namely use:
 {{{
 // intel-17.0.0 fails with internal error 0_76 if vectorization is not
 disabled
 #if __INTEL_COMPILER >= 1700
 #pragma GCC optimization_level 1
 #endif
 }}}
 and would like to apply this very soon as stampede2's intel 18 compiler
 requires this and the next round of xrac allocation will come online on
 Jan
 1st 2018.
