[Jordi Gutierrez Hermoso]

I am forwarding this bug from the Debian Bug Tracking System. Dirk
wants to know if you recommend exceptions or not.

Thanks,

Very interesting suggestion. I am principally in favour, and have only two
concerns

i)   possible overhead, though the gcc manual seems to imply that it is
    affecting size only, not speed

ii)  Policy -- I am not sure if Debian has a view on this either way. I may
    bring this up on the Debian-science list.

Would you mind also asking on the GSL list if there is a general
recommendation in favour, against, or neutral?

Cheers, Dirk
