I'm seeing a crash that affects LLVM 17 and 18, cross compiling on Ubuntu 22.04 for Windows ARM via clang-cl. Headers are coming from the Windows 10 SDK and from Visual Studio 2022 17.4.
I've reduced the code down to the simplest case I can, and this source is attached, along with the bug report files. Commenting out any of the `std::vectors` or the line towards the end containing `emplace_back` avoids the crash. Removing any of these three command line parameters also avoids the crash: `/EHa /clang:-O3 /Zi`. I get no warnings either for `-Wall -Wpedantic` nor from `clang-tidy`.
