spdlog_ex's can throw exception

[elnormous]

You should not store std::string in the spdlog_ex class, because the std::move in the constructor can throw an exception and also rethrowing the spdlog_ex exception will try to copy the _msg which can also throw an exception.

I think you've opened this in the wrong repository. This isn't spdlog.

Oh, I am terribly sorry.
