Hey Ake,
Could you elaborate on that? I mean, I do expect the compiler to have bugs, but
we haven’t seen anything particularly bad so far, just these 2 things:
-The issue with glibc in CentOS 7.4
-An internal compiler error when optimizing certain loops in PETSc with complex
numbers.
Is there any particular bug we should be aware of?

I strongly advise against using the intel 2018.0.128 compiler.
It has bugs!
2018.1.163 works much better.
