I get this with 2.7.2 and 3.2.3 on Debian.
I did some experiments:
The "script" file can contain as little as
with 1 as f:
pass
pass
and the segfault will occur if 'j 3' is issued. It seems jumping anywhere within
the file beyond the context manager will trigger it.
With 2.7 the segfault happens consistently. With 3.2, it's complicated: it
occurs every nth time 'j 3' is issued where n < 5 or thereabouts. However, if it
doesn't happen when the command is issued, it happens when 'exit' is called.
Hopefully some of this is a clue.
Regards,
John
