Forgot to update the status of this one after consensus submitter. The "bug"
only occurs using r13 and older and is due to a lack of "feature" in the older
versions.

OK,thanks for your help.
I can work around using doubles. And I'll try it in matlab 2008B later.
Thanks again.

If you compare
<http://www.mathworks.com/access/helpdesk_r13/help/toolbox/simulink/sfg/sfun.html>
with the current documentation of s-functions, it seems indeed a limitation of
older simulink versions.

Can you work around using doubles? Unless we really need this ourselves, I
guess this will be a WONTFIX for now.

We haven't got that version here, so it's hard for me to check :-( Maybe the
capability has only been added in later versions (I've fixed it on 2008B)

The following procedure fixes this for me (debian lenny, matlab 7.7)

> 1/ open $MATLAB_ROOT/rtw/c/orocos/taskcontext/orocos_taskcontext.mdl,
> 2/ unlock the library (Menu: Edit -> Unlock Library)
> 3/ double click on the DataPort<int> block and
> 4/ change the "initial value" from '0' to 'int32(0)'

But seems to cause the following error for Jack

MATLAB error message:
Error using ==> rtwgen
S-function 2')">'OrocosTestInt/DataPort<int>2'
parameters must be of type double or char for Real-Time Workshop if the
S-function does not have TLC.

Jack, which version of matlab/simulink are you using?
