Minimal code file that triggers the bug

Segmentation fault on compilation of code. 

Platform: Mac OS X
Versions: Apple Clang 11, LLVM Clang 9.0.1 (from homebrew).

I managed to reduce the code to a couple lines that trigger the crash, see the
attached store.cpp. 

The compilation flags I've used were:

/usr/local/Cellar/llvm/9.0.1/bin/clang++ -std=c++17 store.cpp
/usr/bin/clang -std=c++17 store.cpp

See attached files.
