[Octave-bug-tracker] [bug #34852] incorrect column number on error messages

[Jordi Gutiérrez Hermoso]

Follow-up Comment #2, bug #34852 (project octave):

It's difficult to see here because the web interface eats whitespace (use
verbatim ... verbatim tags here next time to enclose code), but the problem is
that the error line is pointing to the assignment operator instead of the
multiplication operator.

A relevant discussion from #octave follows: 



<jwe> We currently don't save teh information about the locations of
individual operators when we are evaluating them.

<jwe> So the matrix multiply function can't print it.

<jwe> And the code that generates the backtrace just looks at the call
stack, which has info only about the locations of the statements.

<jwe> For the line with teh assignment, the location is the location
of the = operator.

<jwe> We should probably just drop the column number from the error
message so it is not misleading.
