As a result of the error, inline_closurecall will incorrectly overwrite an existing label, resulting in code that creates an effect-free infinite loop, which is an undefined behavior to LLVM. LLVM will then assume the function can never execute and an alternative code path will be taken in spite of the value of any conditional branch that is guarding the alternative code path.
