Bootstraping an older version with a newer version might not work.

I got lots of bug boxes with generic instaciations - namely the booch
components. Also: I have sepereate comiles for release and debug - often
one works while the other gives a bug box. 

With 3.15p I had a bug box for OS/2 debug while OS/2 release, Windows
Debug/Release and Linux Debug/Release where compiling fine.

With 3.4 I havn't seen one for a long time - well apart from the "limited
with" ;-) .

And I fear we don't get another one. Wir RedHats incompatible 3.x version
and tree-saa 4.x, compiler development has speeded up. I have the distrinct
feeling that AdaCore has not time for public releases.
