[Qemu-devel] qemu in free(): error: junk pointer, too high to make sense

[nollan <nollan@lavabit.com>]

Hi,

I got this error twice on a FreeBSD 6.3-RELEASE host, once when running 
Windows 2003 Server and another time
running opensuse 11.0 as guests. I did a backtrace and here it is. I 
hope you can help me. Please let me know if there is additional
things you need me to do.
