Segmentation fault
Environment:
2.6.24-27-generic #1 SMP, Ubuntu 8.04.4 LTS, Both Python 2.5.2 from distro repo and Python 3.1.1 compiled by me. But crash seems to be platform and version independent.
Comment:
Should throw RuntimeError: maximum recursion depth exceeded instead of SIGSEGV?

confirmed on 3.2 trunk. This happens on access and not during the repr. See the attached crasher.py (3 megs of "[0]") |

> This is a close duplicate of issue5765. Except that #5765 is apparently not a 3.x issue, while this example, WinXP, 3.1.2 crashes the command window in about 5 sec, while IDLE gets locked (^C does not break). |

Correction to the last message. Issue5765 was a 3.x issue. It was fixed for 3.3+, and it was decided to not fix it for 2.7 and 3.2. This issue is not reproduced in 3.3+. |
