Error - "some elements undefined in return list"

[nit ar]

Hello Octave maintainers !
 
An error is caused by the following example (test.m script and testf.m function) when the script calls a function and attempts to return structure values to new fields of a structure which already exists.
 
There is a strange behavior in the following example: while the call on the 3rd line is successful, the call on the 4th line fails (names of the new fields are 2-letter ?).
 
See also strange d.ca.a conetnts printout on the console !
 
This may be related to the patch provided by
http://www.cae.wisc.edu/pipermail/bug-octave/2007-October/003645.html
which has fixed another problem of assigning values to an output list. As far as I remember the current error didn't occur on ver 2.9.15.
 
I am currently running MSVC version 2.9.16 (compiled by Michael Goffioul)
