--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Because debugging information contains many different things.
Stuff like:
1) Types
2) Line information

Types can increases the size with templates too.

You should be able to look the debug info to see where the increase is located.

Also debug information does not get mapped into the memory when running the
program so it won't change the behavior at all; only the on disk size.
