I have researched the logs a bit.

In PolyORB's log:

Date: 2009-04-23T17:19:23

[PolyORB @ 143261]
(System.Partition_Interface.Allocate_Buffer):
 Removed, no longer used.

According to GCC's log, exp_dist.adb has been emitting calls to the
procedure since 2004-12-08, with the addition of:

    2006-10-31  Thomas Quinot  <quinot at adacore.com>
            * exp_dist.adb
    	(Build_From_Any_Function, case of tagged types): Add missing call to
    	Allocate_Buffer.

My conclusion: this is another impedance mismatch between PolyORB and
GCC.  I guess we'll have to wait until AdaCore publishes the GCC patch
that stops exp_dist.adb from emitting these calls.  I'll backport it
into gnat-4.4, too.

In the mean time, maye you should revert to an older version of PolyORB
(i.e. before revision 143261 in Subversion).  I would suggest, for now,
revision 1239b292361c6ad7d22fee454bb18c72b876888d on branch
com.adacore.polyorb.debian in Ada-France's monotone database; it is
based on r141128.
