Hi Simon, It is very strange. I use Ubuntu 11.10 and my parameters are:
hamsin@hamsin-pc:~/bin/sage-5.0.beta4$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 11.10 Release: 11.10 Codename: oneiric hamsin@hamsin-pc:~/bin/sage-5.0.beta4$ gcc --version gcc (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1 Copyright (C) 2011 Free Software Foundation, Inc.

This probably occurred because a *compiled* component of Sage has a bug in it and 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. ------------------------------------------------------------------------ /home/hamsin/bin/sage-5.0.beta4/spkg/bin/sage: line 304: 16967 Segmentation fault sage-ipython "$@" -i Can anyone reproduce the same bug on Ubuntu?
