Two solutions here:

1) put the line number information into the message string when you raise
the exception

2) use Cython instead of plain C, as Cython will automatically generate
readable stack traces for you, also for non-Python functions.

Funny that you (being the OP) ask *me* what kind of line information *you*
want.

Then please explain what kind of Python line number you expect to find in C
code.

Hint: providing details often results in getting helpful answers.
