Due to the low-leveled-ness of the problem, I'd guess it's a qemu//lib64/libtcmalloc malloc bug, and not directly related to ovirt. Please report the precise version of qemu,kernel,libvirt and gperftools-libs to qemu-devel mailing list and the complete stack trace and qemu command line, if possible.
