#1074 refactored some of the code to enable the failure function to throw. This made it so when the LogMessageFatal class was used, the error ended up being printed differently.

Before:
LOG_AT_LEVEL(google::LogSeverity::FATAL) << "Crash: Hello world!"; ->

Thank you for the PR.

Unfortunately, the CI builds are now failing. Please inspect the runner output to identify the reason.

// We really want [[noreturn]] on the destructor so the compiler can use it.
// We really just want to reuse the parent class's destructor since it has all
// the right logic in it.
LogMessage::~LogMessage();

The destructors in a class hierarchy are generally called in the reverse order of construction. Explicitly invoking the base class destructor means that the base class destructor will be called a second time. However, at that point the object no longer exists. I suspect this is UB territory.
