Dear all,

we have written a small OCaml program that interfaces
to some C++ code.  For all the classes we have interfaced,
we have defined the required `struct custom_operations' that
is then registered with `register_custom_operations()'
and referred to in calls to `alloc_custom()'.  The finalization
functions invoke `delete' on the pointer embedded into the
OCaml value.  We do this with 6 different C++ classes that
are all handled in exactly the same way.

Then we have a small test program written in OCaml whose
last line is

   at_exit Gc.full_major;;

and for which valgrind (http://valgrind.kde.org/) says
we have memory leaks.  We have then verified that the
finalization functions for 2 of the created C++ objects
are never called.

As we are really beginners at OCaml programming, we are
sure we are missing something, but we don't know what.
Isn't `at_exit Gc.full_major;;' supposed to collect
_everything_ at program termination time?
Thanks in advane for your advice,

      Roberto
