Segfault minimal reproducible example

Here is the code and the error, produced by clang compiler both on the latest
trunk version and some previous versions (clang-9.0, clang-8.0):

https://godbolt.org/z/H523mO

I attached the same code here. It produces Segmentation Fault, when compiled on
Linux 4.19.59-1-MANJARO with a command:

clang++ -std=c++17 -g test_main.cpp

It doesn't produce any errors without -g flag.

clang version 8.0.0 (tags/RELEASE_800/final)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin
