Comment(by rbeezer):
alpha3-prerelease segfaults during testing, without patch. Errors,
followed by system info. I can follow up with more testing, if requested.

------------------------------------------------------------------------
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.
