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.
/opt/sage/spkg/bin/sage: line 671: 10989 Bus error               sage-notebook "$@"

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

THis is the output of sage -gdb:

Along with sage, other programs in my system were also behaving wierdly and showing errors like /tmp/ folder is full even though that partition had > 200GB free.

I just cleared the folder /tmp/ (It has content of size 1.8 GB) and this problem is gone. Not sure how it works but, it worked!

Looks like your file system is damaged. Check smart data and make sure your backups are in order :-)

Did yesterday's upgrade pull in a new glibc version by any chance? Your best bet is probably to recompile Sage.

Actually glibc isn't there in the updates that were installed yesterday. I found out how to fix this problem. I"m going to post it as an answer.
