controlled types and streaming

controlled types and streaming

[anders brolien]

Hello,

I am using gnat 3.13p solaris.

I have stumbled into some problems when trying
to transfer objects over an tcp/ip network
using the classes default 'input 'output methods to
produce a byte stream.

I works fine so long as the class don't
inherit from ada.finalization.controlled.
Should this be possible to achieve ???

Have been looking at system.finalization_root
and the two pointers in the root_controlled class
don't seem to be right to transfer to another CPU.
Local object refs ...

Does this make any sense ??

I turned this problem up a short time ago and posted questions here
about it. The dominant opinion is that it *should* work, but is an
apparent bug with GNAT 3.13p. You might want to post an example that
duplicates the error and we could compare notes to see if it is the same
problem.
