[Bug 1320144] Re: kvm crashes with malloc.c assertion failed and other errors

[f3a97]

** Description changed:

  My Win7 VM running on KVM keeps crashing lately.
  
  I cannot say when it started to do so but I can say that this was not
  happening at all some weeks ago.
  
  From the qemu-kvm log file related to this VM just after the crash I
  have found what follows:
