Space penalty appears to be about 5%. However, this stuff sits in its
own section, and usually won't be paged in unless touched, so it should
not affect physical memory consumption, just disk space.
If you don't want the data present all the time, you might want to
use .debug_frame instead of .eh_frame, e.g. by using -g1 instead
of -fasynchronous-unwind-tables.
