I'm tracking this bug here:
https://bugzilla.redhat.com/show_bug.cgi?id=853408
Does anyone recognize this segfault on shutdown when using either a
console or a virtio-serial char device?
It's only caught in Fedora because we compile with 'fortify source' so
the attempt to modify a negative offset in an fdset is caught.
Probably it just overwrites a random bit of memory for everyone else.
