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

[John W. Eaton]

Follow-up Comment #13, bug #61841 (project octave):

I think the empty matrix is appearing when the stack struct array is extended.
 The code that eliminated the invalid (= -1) column field from the stack frame
struct seemed like a good idea but then when the stack struct array is
extended to another element, the default is for elements to be filled with
[].

The attached should fix the error, but we will need to do a better job of
ensuring that line and column info is always valid instead of sometimes being
set to -1.  But maybe it is better to leave the invalid values there and work
to fix them over time.
