> There seems to be a gcc bug related to {{std::to_string}} that only appears
> in {{-O3}} builds. It can be seen in something innocuous like
> {code}
> return Status::Invalid("Float value ", std::to_string(val), " was
> truncated converting to",
> *output.type());
> {code}
> where val is NaN. I haven't found a canonical reference but using something
> other than to_string for the formatting (here just letting
> {{std::ostringstream}} take care of it) makes the problem go away
> I wasn't able to reproduce the issue with gcc-8
> EDIT: it's a known bug in gcc
> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86274
