The problem also happens with GCC 3.4.1

Regression?

The behaviour with GCC 3.3 is bogus as well. There should be no error message.
In addition, both the error message with GCC 3.3 and the crash with GCC 3.4/4.0
go away by commenting the representation clauses
for base'size use 64
for base use record
....
end record;

As you probably noticed, this code attempts to represent in Ada the descriptor
of a segment in the x86 architecture.

Ada is not release-critical; removing target milestone.

I agree that this is not a regression. If you could put less generic summary
line, that would be really helpful. Imagine that everyone getting a compiler crash
used the same summary: things would get very confused...
