<<Since the benchmark gcc is never fed any erroneous source while running
the benchmark, none of the error-handling stuff is ever executed. With
profile-based optimization it's possible to move a lot of that stuff so
it never gets paged in; that's a significant win. The same conditions
don't apply when running gcc normally, so this is fairly artificial.

Why would it be paged in if it is not executed?
