Details:

I am using octave 4.2.1 patched with changeset 7eb0077e86f0. 

Let's use a simple one-line script with a syntax error in the format specifier
string:


t=sprintf('hello %');


The generated error report is different when I execute the script in batch
mode comparing to when the script is executed at the interpreter command line
(both in CLI or GUI mode). In the first case the given error is:

$ octave test.m
warning: function ./test.m shadows a core library function
error: sprintf: invalid format specified
error: execution exception in test.m

In the second case:

octave:1> test
error: sprintf: invalid format specified
error: called from
    test at line 1 column 2
