I'm using a template-based model implementations, where in order to make logging work I need to use a little bit more complex logging initialization.  In particular, I have a static method in a class that constructs name on the fly, based on names of parent classes.  (You can check https://github.com/NDN-Routing/ndnSIM/blob/master/model/fw/per-fib-limits.h for my a slightly crazy example of that.)

Currently, when LogComponent is initialized, it stores a supplied pointer const char* to a member variable, without actually copying the string.  In all current cases this is fine (as it points to a static data), but in my case---dynamic string creationg---that caused a disaster.

So, my suggestion is to just change an internally stored type in LogComponent to std::string, which involves two small changes:

Do you think it is a reasonable change?
