Do you happen to have a code example that causes this ICE?

[tupshin]

Not easily. It was one stop on a complicated refactoring. If I can get back to that state, I'll link you.

[tamird]

Not actionable without a test case. @steveklabnik is it appropriate to close stale issues such as this?

[steveklabnik]

Yes, it's been a number of months, with no activity.

@tupshin if you can reproduce, please let us know, and we'll re-open. Thanks
