[issue8070] Infinite loop in PyRun_InteractiveLoopFlags() if PyRun_InteractiveOneFlags() raises an error

Xavier de Gaye added the comment: The infinite loop may occur if one of the functions called by PyRun_InteractiveOneObject() returns persistently -1. This may be the case when there is no more memory and is handled by issue 30696. It is not possible anymore to reproduce

Tim Lesher tles...@gmail.com added the comment: I just hit this one myself, and was about to write a bug and patch. On reviewing the patch: 1. This really has the same issue as the original code: it detects one of a few known return values, and will infinitely loop on an unexpected return
