test case code
Starting with clang 12.0.0 (Fedora 34), some C++ code no longer compiles,
throwing the error message in the Summary of this ticket.
I boiled the code down to a test.cpp which exhibits the issue (could probably
boil it down further, but I hope this is good enough). When I put it through
godbolt.org (godbolt.org/z/ToceWcEG7) it compiles in GCC and clang older than
12.0.0, but exhibits the same failure in trunk.
Please let me know what else you need to know to help address this, and thanks
in advance.</pre>
