I should note that this at the moment at least seems perfectly reproducible for me.

[Daniel Uber (djuber)]

I have had the same build experience on Darwin (sb-sprof test fails). Enabling --with-sb-threads resolved this issue for me.

[Douglas Katzman (dougk)]

obsolete most likely, can't repro it now.
