| Georg, I hope you don't mind me assigning this to you. Feel free to unassign. A colleague pointed me to section 5.7 in the old ref doc: http://docs.python.org/ref/shifting.html It says that shifting operations lose data on overflow. This info is outdated based on PEP 237. I suspect there may be other inaccuracies related to int overflow. So the purpose of this bug is to point out the specific problem as well as to log that we need to find all invalid references to overflow. | ||

| Just jumping in to say the colleague Neal refers to is me, and I'm interested in the resolution to this bug. Thanks in advance for your help. | ||
