Patch fixing the failures

Massive as an failures appeared on x86_64-apple-darwin14 between r217514 (none
with patches) r217602 (356 with the same patches).

The attached patch fixes these failures. Note

(1) I don't understand what has changed to explain the failures.
(2) The patch is a mechanical addition of a '?' after the blocks '(in ...)'.
There may be a better fix.
