I didn't do anything to the sage install.(I have upgraded by system yesterday) And suddenly today sage stopped working and this is being displayed.

------------------------------------------------------------------------
Unhandled SIGBUS: A bus error occurred in Sage.
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.

I am using arch linux x86_64 running sage 5.0.1(manually compiled). How can I get it working again?
