| Sage Version 4.4.3, Release Date: 2010-06-04 |
| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
------------------------------------------------------------
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. so this was originally a sage 4.4.1 upgraded to 4.4.2
and this afternoon to 4.4.3.
I have a backtrace that stops at ginac:

Anything else I should look for? I am personally suspecting the python upgrade
not to be very smooth.
