13739	Illegal memory exceptions when saving state (Fedora21/Centos7 Guests, Windoes 7 Host))	tsujamin		"I have a pair of Centos7 x86_64 VM's and a Fedora21 x86_64 VM which always virtualbox when I save their state. All VM's have the latest guest additions installed. My pair of Centos6.6 VM's do not suffer this problem.

Virtualbox Version: 4.3.20
Host: Windows 7 x86_64
Fedora kernel: 3.17.4.301

Find attached the most recent log from the fedora instance. This one crashed with ""Instruction at 0x0 referenced memory at 0x0 that couldn't be written"" however the actual memory/instruction addresses do change
