Hi,
the line numbers of inspect.getinnerframes are
different from traceback.format_exception.
This results in wrong lines being shown in cgitb.
An example is below.
I looked at the source of both methods. One uses f_lineno (wrong)
the other tb_lineno (correct).
I use python 2.3.3
Is this fixed in a newer version?
See:
===> python tb.py
