This is a serious security regression. If you are not able to fix this quickly, please revert the change that introduced it. If this doesn't affect a release branch, or has not been properly classified for severity, please update the Security_Impact or Security_Severity labels, and remove the ReleaseBlock label.

Removing release block and security restrictions. This is not a real bad-cast. It's just an issue with our tooling not deduplicating the typeinfo for that particular type in the standard library. This is seen in the error message: "Bad-cast to std::__1::locale::__imp from std::__1::locale::__imp". As you can see, the types are the same.
