Subject: qemu crashed when starting vm(kvm) with vnc connect
Date: Tue, 2 Apr 2013 09:02:02 +0000	[thread overview]
Message-ID: <D3E216785288A145B7BC975F83A2ED103FE154C1@szxeml556-mbx.china.huawei.com> (raw)

I start a kvm VM with vnc(using the zrle protocol) connect, sometimes qemu program crashed during starting period, received signal SIGABRT.
Trying about 20 times, this crash may be reproduced.
I guess the cause memory corruption or double free.

The backtrace shown as below:
