[Pkg-octave-devel] Re: Error message about "empty_list_elements_ok"

[Edward C. Jones]

Some more information: In the octage-forge source code 
(octave-forge_2004.11.16.orig.tar.gz) in file "main/image/imread.m", 
lines 106-8 are:

try save_empty_list_elements_ok= empty_list_elements_ok;
catch save_empty_list_elements_ok= 0;
end

There is no bug; just a design surprise. See the octave docs, section 
12.9 on try statement:

No warnings or error messages are printed while body is executing. If an 
error does occur during the execution of body, cleanup can use the 
function lasterr to access the text of the message that would have been 
printed.

There has got to be a good way of telling is an error happens in octave.

Sorry to bother you,
Ed Jones
