Unstable option: Polymorphization.Area: Code generation parts specific to LLVM. Both correctness bugs and optimization-related issues.Category: This is a bug.Call for participation: An issue has been fixed and does not reproduce, but no test has been added.Issue: The compiler panicked, giving an Internal Compilation Error (ICE) ❄️Relevant to the compiler team, which will review and decide on the PR/issue.This issue requires a build of rustc or tooling with debug-assertions in some wayThis issue requires a nightly compiler in some way.
