I'm unable to reproduce this (sorry). I noticed before
that sometimes, the interactive Python interpreter
segfaults irreproducable: only now, it was two times in
succession but not more than two times. I never
encounered this problem while executing Python programs
from scripts.

I suspect this is a bug in the C library. To find out for
sure, one would have to study the relevant assembler code in
glibc in detail.
