You're using testing, which is now in the middle of the transition from
gnat-4.6 to gnat-4.9 as the default compiler.  Use unstable, perhaps in
a chroot[1] and all will be fine.

I'll try to have a look at the bug you reported; I think I must take the
blame for it, since it happens in Debian and not in GCC built from
pristine sources.

Thanks for reporting this problem.
