Passing a std::string vs a const char* to boost::bind should have as
close as possible to same behaviour as passing that parameter to a
normal C++ function..

That code is safe - the lifetime of string literals is the lifetime of
the program.

Just to be clear, using char*s as strings is tricky and error prone -
but that is a problem with C++, not a problem with boost.
