<snip/> I'm wondering what people think of making use of this in libvirt ?
Apart from what have been said (I share the same concerns) I like the idea. All the "limitations" - we already have them. You have to initialize variables even when using 'goto cleanup'. But with this feature we can save few lines of code in a lot of functions. Therefore I'm up for it. BTW: do you know when was this introduced? Whether this feature is available on all prehistoric^Wstill supported systems like RHEL6.
The docs are non-existant on when this appeared, but I just checked out gcc 4.1.2 and found plenty of references to attribute cleanup. This covers RHEL-5 vintage, so it looks fine.
