Hi,
Recently I build qemu-kvm on 32bit RHEL5u4/RHEL5u5, it will fail on fuction
"vhost_dev_sync_region". But RHEL5u1 system is fine to build.
Did anyone meet similar issue?
qemu-kvm commit: 59d71ddb432db04b57ee2658ce50a3e35d7db97e

Appears to be a gcc bug. I opened
https://bugzilla.redhat.com/show_bug.cgi?id=624279 to track this.
Meanwhile, installing the gcc44 package and building with it
(./configure --cc=gcc44) appears to work.
