I used gcc 4.0.2 as the bootstrap compiler.  I believe that the error
doesn't occur when gcc-3.4.4 is used.

Is this issue still present ?

If the issue is with the bootstrap compiler, there's not much we can do.

I last retested a build with Ada enabled about a week ago and the
problem was still present.

Bootstrap compiler is GCC.  This doesn't occur on linux, but it
doesn't need the -mdisable-indexing hack.  I'll try to investigate
further.

Well sure, you can't bootstrap GNAT with anything else than GCC ;-)

Is this the same version of GCC ? Could you try with another version ?

Thanks.

Well, I didn't want to confirm it (do not have the set up), I just
wanted to reopen the bug (as in, remove the "WAITING" state).

Anyway, no big deal.

The error doesn't occur with 3.4.4.  I have a build of 4.1.0 underway.
If the build is successful, I will install and test it to see if the
miscompilation is still present with 4.1.  There was a recent fix that
should make debugging easier.

Is GNAT still being maintained in the 4.0 branch?

Yes, although only critical changes go there (as you would expect for
a release branch).

Still fails as of 2006-02-05 with 4.0.2 bootstrap.  Not present in 4.1.0
20060127 (prerelease).

Given that 4.1.0 has been released and issue is fixed there, closing this
PR.
