Dear Maintainer,
* What led up to the situation?
Using std::filesystem.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Have to use C stat function, which is not good when others add code.
* What was the outcome of this action?
Temporarily fixed.
* What outcome did you expect instead?
Permanently fixed.
This was fixed in GCC 8.4. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91947
and https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=761696abfe0a772315449e3d2b57de76756f5953
