The fix makes sense - on the put side, you pass 'short' to a var-args function, which gets promoted to 'int', so the va_arg must grab the value from the promoted type. But on the get side, you pass 'short*' to a var-args function, which is used as-is, and if you tell dbus to deref an 'int*', that would explain the stack-smashing. But yeah, waiting for a build confirmation never hurts. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
