[issue13027] python 2.6.6 interpreter core dumps on modules command from help prompt

Balachandran Sivakumar  added the comment:

But this doesn't happen in other versions of python. Also what I did is 
something like this:
bala@bala$ python
...
...
>>> help()
...
...
...
help > modules

It is after this I see it dumping. And I see this only with 2.6.6. I have other 
versions in other machines(all running Debian) and none of them crash. In my 
opinion, a seg fault doesn't look good. Of course, if we can't do much about 
it, I don't have a problem closing it down. core But a segv looks bad to the 
beginner, who is more likely to use this. In fact, I was using that just to 
show a beginner how to get help :(
