The built was from a clean checkout.
auto-host.h seems to be correctly created during the build. I see this after
the build failure:

That's correct. I'm just building in-tree and using 'git clean -df' to reset
everything back to a pristine checkout state when I need to.

Thanks. I'll keep an eye on both of them, and will report here if the fix for
either of those fixes the segmentation faults I'm seeing.
