Speaking of, now that StackTrace has been accepted into Boost, are you
considering migrating that code to use it instead?
Somewhat related, the docs for error_code_extended::backtrace() specify
that the returned value must be freed. Is that referring only to the
array itself or must the individual char* within the returned char** be
individually freed as well? Why doesn't this just return
std::vector<std::string> or some kind of smart pointer for avoidance of
doubt and exception-safety? It feels like this is allowing
implementation details to escape unsafely.
