Description
I was trying to build google benchmark with IBM XL 16.1.1 and it crashed the compiler. Not sure if anyone wants to investigate a workaround or so.

In the end this is clearly a compiler bug since it at least shouldn't crash. But we have been working around compiler bugs in our codes not sure what googles philosophy on this is.
Forgot to paste system info this is a IBM Power 9 system with NVIDIA V100 GPUs in it running ReadHat 7.5. (kinda like Summit). I can't post to much more details unfortunately but here is uname output:
Linux XXXX 4.14.0-49.8.1.el7a.ppc64le #1 SMP Mon May 28 07:06:43 UTC 2018 ppc64le ppc64le ppc64le GNU/Linux
