ObjcExceptionPreprocessor is a 'reasonable effort' attempt to catch an NSException minidump at time the exception is thrown as opposed to when the application terminates due to the exception. If multiple exceptions are thrown at the same time, Crashpad should correctly report the final uncaught exception, but the minidump may not represent the full `caught-at-thrown` minidump. - Don't assume ObjcExceptionPreprocessor throws an NSException. - Don't retain/release the exception. Instead of calling isEqual, just use a simple pointer comparison. - Make last_exception atomic.
