r171648 (just before the first IRA change) does not show the regression.
r171649 did not build for me - probably because it was the first of a few IRA
patches.
r171713 did build, and does show the regression.

I think it is an IRA thing, as there aren't many non-IRA changes between the
good and bad revisions.
