It doesn't (always) matter...

Hi,
I've had exactly the same problem using gnat-3.13p and the Booch Components
(bc-20000219). When using the managed memory pools from the components the
program would not close *after* executing all my code correctly. In the
debugger I've seen this error then... For me the occurence of this error
depends on the size of my lists and can (seemingly) be avoided using
unmanaged storage. And gnat-3.14p, gnat-3.15p and gcc-3.2-gnat do not work
at all for me due to compiler errors :-(

So it might be an Error in the compiler finalization code or probably a
problem with the booch components itself. But I did not find the time to
look more closely yet.

Otherwise I am very pleased with Ada and gnat, looking at a colleague and
his C++ struggles :-)

Regards,
Alexander
