After trying prime_factors(2^100000000000000) I received all this

Saved trace to /home/esteban/.sage/crash_logs/sage_crash_zXpf5F.log
Unhandled SIGSEGV: A segmentation fault 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.
What is that? Should I do something? Did it (unsuccesfully) try to autoreport bug?
