Hi Bruno,

>I ran into an ACE behavior which I don't understand.

Thanks very much for your email.  To ensure that we have proper
version/platform/compiler information, please make sure you fill out
the appropriate problem report form (PRF), which is in


or in


in older versions of ACE+TAO.  Make sure to include this information
when asking any questions about ACE+TAO since otherwise we have to
"guess" what version/platform/compiler/options you've using, which is
very error-prone and slows down our responsiveness.  If you don't use
the PRF, therefore, it is less likely that someone from the core
ACE+TAO developer team will be able to answer your question.
Naturally, we encourage and appreciate other members of the ACE+TAO
user community who can respond to questions that they have the answers

It's really not clear what you are trying to do.  Please send a small
example that illustrates the problem.
