This turns out to be a backport issue. `release/15.x` (https://github.com/llvm/llvm-project/tree/release/15.x) uses C++14 and structured bindings trigger warnings in GCC/Clang and errors in MSVC.
My bad that I did not think of the difference when crafting the patch.
Pushed a trivial commit to release/15.x to avoid structured bindings.
