Good to know.

There should be a way to display the code of that particular line that
causes problems, so by looking into the code you may be able to find
the line itself.

One of the exeptions when that problem with line numbering happens is
when try statement is used. OK, I will probably be not able to help
more at the moment...

Well.. when I had a problem like that in the past I simply inserted
some empty lines and checked if the numbers shown by debugger increase
or do not change. In that way, after some trials, one is able to find
an exact location of the line where the problem happens.
