error return without exception set

[Will McGugan]

Hi,

Can anyone suggest a likely cause for the following exception...

Exception exceptions.SystemError: 'error return without exception set'
in <generator object at 0x0345CF30ignored

Thanks

The "Exception ... ignored" part is probably caused by an exception in a
finally block during garbage collection:

>>def f():

.... try:
.... yield 42
.... finally:
.... 1/0
....

>>g = f()
g.next()

42

>>del g

Exception exceptions.ZeroDivisionError: 'integer division or modulo by zero'
in <generator object at 0x401d2fecignored

The "error return without exception set" part looks like a failed
consistency check in ceval.c -- perhaps caused by a broken extension
written in C.

But you'd have to give some more context.

Thanks for the explanation. It happens when I'm debugging a wxWidgets
application with Komodo, but I can't trap it. I'm guessing it must be a
Komodo issue, because I dont get it if I run it without the debugger.

The error happens in PyDev for Eclipse also -- only while debugging.

It happens with or without wxWidgets; I've always assumed it's a pydev
issue.
