Probably invoking UB due to the string concatenation producing a Twine, which is only good as a temporary. If you remove the use of auto that’ll be more obvious, probably.

There’s a lint warning for using Twine values as temporaries if you’re using clangd I believe. I’d recommend using typeStr = (...).str() instead.
