[Xotcl] serializer bug: searchDefaults

[Stefan Sobernig]

I just stumbled over buggy behaviour of
the XOTcl Serializer with respect to inheritance
relationships and searchDefaults, originally encountered
under AOLServer.

% info patchlevel
8.4.14
% set ::xotcl::version
1.5
% set ::xotcl::patchlevel
.4

I could also re-produce this behaviour with
the most recent xotcl release, 1.5.5 (as there
were no changes to the serializer between 1.5.4 and
1.5.5, I assume)

The snippet attached can be used to reproduce
this behaviour in a non-AOLServer environment.
Interesting enough, the critical part
is to create an instance of the super class BEFORE
declaring the sub class. Commenting the line
"Super create super" yields a sound stream, creating
super yields a broken one.

To reproduce, do the following:
tclsh searchDefaults.xotcl
tclsh /tmp/stream

I tried to have a more thorough look but
I couldn't illuminate myself ...
