Correct.

Yep. The debugging information is only used by debuggers such as gdb. This
stuff is in the elf/coff/aout file. When the loader loads the elf file it only
looks at the sections that contain code and data. ie. it ignores the extra
debugging information. Stripping the debugging information does not alter the
code and data sections so everything gets loaded into memory the same way as if
the debugging information was present. It just means that you can't debug the
source. Of course you can still look at the assembly with a disassemlber.
