Hi, I'm no longer able to compile SPEC CPU 2017 after this due to an error in
510.parest_r:

I think it's based off this
https://github.com/dealii/dealii/blob/master/source/fe/fe_tools.cc, but
unfortunately what SPEC is using seems to be quite out of date. I can try
plugging this into creduce and see if it gives a reproducer.
I'm not a C++ expert by any means so maybe this error is correct. Is there a
flag that could be used to workaround this?
