We are testing LTO internally and have not run into this issue IIRC. But on the other hand, we are doing a straight compilation (I.e. not doing it in parts as you said you were). Even so, you are right, we should have public lnt LTO testers.

(I sent a tarball earlier to the list on how to reproduce it). Bugs like these will not be caught any more with the standard LNT tests, true, but there's also point 2 below...ping

So, the way to go would be to have LNT on all buildbots (in the long run) testing with and without LTO (and possibly other variations), so we can have. a coherent story and an easy way to reproduce errors locally.
