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?

It has bugs! 2018.1.163 works much better.
