I'm using a "ConnectionCallback" function to automatically name lines, that are connected to a inport of a subsystem.

But there's one reproducible problem occuring, if I change portnames of other blocks. Matlab crashes with following error message:

"------------------------------------------------------------------------
Assertion detected at Mon Jul 26 15:26:59 2010
------------------------------------------------------------------------
Assertion failed: Forced Assertion at line 714 of file ".\memmgr\mem32aligned.cpp".
Corrupted memory block found
....."

This is my "ConnectionCallback" function:

---------------------------------------------
function [] = foo(ph)

% get block name
sigBlockName = get_param(gcbh, 'Name');

% get connected line
l = get_param(ph, 'Line');

if l ~= -1
% set name of connected line
set_param(l, 'Name', sigBlockName);

else
% get name of disconnected line/port and replace it by empty string
l2 = find_system(gcs, 'FindAll', 'on', 'Type', 'port', 'Name', sigBlockName);
portO = get_param(l2, 'Object');
set(portO,'Name', ''); % THIS COMMAND CAUSES AN ERROR!
end
end
---------------------------------------------
Would be nice, if someone could tell me what the reason is.

I've forgotten to tell, that a crash only occurs if I disconnect the line from inport.
Deleting the line (and/or the hole subsystem) works fine.

done...
Hope I'll get a answer soon.
