--- Comment #12 from Jonas Devlieghere <jonas at devlieghere.com> ---
I was too fast in closing this issue. I wasn't using a preprocessed file and a
change in libcxx explains the biggest time differences. Taking this out of the
equation still leaves us with enabling debug info being about twice as slow as
without with exceptions disabled.
