I don't follow Ubuntu; just keeping up with Debian is enough work :)
But in theory, they should be quite close as the same person is the
maintainer of GCC in both Debian and Ubuntu.  He also maintains GNAT
in Ubuntu.  Now it can be that other packages like the kernel and
glibc, or their configuration, introduce subtle differences between
Debian and Ubuntu.

Report problems through the Debian bug tracking system as precisely as
possible.
If you discover a bug in gnat-4.4 which happens not to be present in
GCC 4.5 or 4.6, I'll try hard to backport the fix.

As I've said many times before, not reporting a bug is the surest way
to never see it fixed.
