You are correct. Modern compilers make sure the symbols are separate and
OS don't even load those areas of the binary unless they need to answer
a stack trace OS call. All it means is a (much) larger binary size on disk.
Running under a debugger is slightly different, where the debugger will
manually load the symbols separately for its own uses.

The reason distros such as Debian and Ubuntu strip symbols is to improve
their disk package sizes and install times. They also often provide a
second package with the non-stripped binary named *-dbg.
