[issue7985] access to infinitely recursive list

[LukMak]

New submission from LukMak <lmakowsk at volt.iem.pw.edu.pl>:

Execution:
>>> l=[]
>>> l.append(l)
>>> l
[[...]]
>>> l[0]
[[...]]
>>> l[0][0][0]
[[...]]
>>> eval('l'+'[0]'*10)
[[...]]
>>> eval('l'+'[0]'*666)
[[...]]
>>> eval('l'+'[0]'*999999)
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?
