Unhandled SIGSEGV: A segmentation fault occured in SAGE.
This probably occured because a *compiled* component
of SAGE has a bug in it (typically accessing invalid memory)
or is not properly wrapped with _sig_on, _sig_off.
You might want to run SAGE under gdb with 'sage -gdb' to debug this.
SAGE will now terminate (sorry).

Oops, IPython crashed. We do our best to make it stable, but...
A crash report was automatically generated with the following information:
- A verbatim copy of the crash traceback.
- A copy of your input history during this session.
- Data on your current IPython configuration.
It was left in the file named:
'/scratch/wstein/sage/ipython/IPython_crash_report.txt'
If you can email this file to the developers, the information in it will
help
them in understanding and correcting the problem.
You can mail it to: Ville Vainio at [email protected]
with the subject 'IPython Crash Report'.
If you want to do it now, the following command will work (under Unix):
mail -s 'IPython Crash Report' [email protected] <
/scratch/wstein/sage/ipython/IPython_crash_report.txt
To ensure accurate tracking of this issue, please file a report about it
