Yeah, I saw what you as I looked at the commit log while trying to
understand why there were invalid strings appearing when the code
looked like it was impossible. Certainly I found it very very odd.
I didn't just revive a 2 year old patch without taking a look at
the code.

Hmm, it would seem that you're right - I have retested on a fresh
clone. I did checkout v7.1.0-rc1 before running the first build that
I saw the invalid string on as I'd been on some hacked up & fossilised
version prior to that. Perhaps some build artifacts were not correctly
removed, consider me quite confused! I do recall the configure script
saying something about my build directory when I kicked it off, so
it is likely down to that.
Unfortunately my bash history is out of order so I will not be able to
replicate the conditions, having many terminals open does have it's
downsides.
> Please. Please make sure that you are testing the right version of QEMU.
Heh. Please, please give me some allowance for reasonably believing I
was in fact on the latest qemu/master after checking it out and building!
I guess this patch can then be safely ignored :)
Glad to have cleared this up as I was rather confused by what I saw.
Thanks Tsukasa/Alistair.
