[Octave-bug-tracker] [bug #61841] rethrowing an exception leads to an internal error

[Rik]

Follow-up Comment #8, bug #61841 (project octave):

We can stop the problem by changing the code in error.cc in the function
make_stack_frame_list.  However, I think it would be better form to change the
code that produces the column numbers so that valid data is always created.

If we were to modify error.cc then this code


for (octave_idx_type i = 0; i < nel; i++)
      frames.push_back (frame_info (file(i).string_value (),
                                    name(i).string_value (),
                                    line(i).int_value (),
                                    (have_column
                                     ? column(i).int_value () : -1)));


could be changed to


for (octave_idx_type i = 0; i < nel; i++)
      frames.push_back (frame_info (file(i).string_value (),
                                    name(i).string_value (),
                                    line(i).int_value (),
                                    (have_column && ! column(i).isempty ()
                                     ? column(i).int_value () : -1)));
