New submission from Simon Chopin <[email protected]>:
This issue occurred at least in Python 2.7, I haven't checked in other versions.
When stepping on a return statement, pdb calls the return value __str__()
method to display it at the end of the line. Only, it doesn't handle the
potential exceptions raised within those functions.
An exemple would be:
import pdb
class A(object):
def __new__(cls):
pdb.set_trace()
return super(A, cls).__new__()
def __init__(self):
self.value = "Foo"
def __str__(self):
return self.value
pdb.run("A()")
When using the step by step, pdb will be interrupted by an unhandled
AttributeError.
