I don't know if you can have a conformant implementation, but to be honest, I never really thought about it. Non-conformant (subtly or not-so-subtly) compilers are something that I have come to accept with resignation. I may not like them, but software has to be written, and it's not going to wait for another team of developers to get their compiler right. At the moment, each one of the two codebases I'm maintaining has about a dozen workarounds for compiler bugs. One of the compilers is already at its 6th major version. It's things like these that bring a smile to my face whenever I see people valiantly calling for rewriting everything in Rust :-).
