The most confusing thing about this whole thread (besides the lack of
logs so we're just guessing what's going on) is why this problem is
suddenly happening on clang 3.7.x (I guess it's 3.7.x here) when that
has never been a problem before?  We needed to add the long-call option
when testing clang 3.8, but why do we suddenly need it on clang 3.7
that hasn't needed it for months?

This very much has the feel of slapping a bandaid on something that
needs a better diagnosis (there may be internal bleeding).  If we don't
understand why it's failing, it doesn't make sense to try to fix it
with the "cure" for a different problem.  (Maybe we never understood
the clang 3.8 problem.)
