Sorry if this is a repeat, but I'm not sure if this has been resolved
yet, as I'm not on any of the mailing lists where it would be posted
and google isn't revealing anything besides this mail I'm replying to
(please keep me on CC in replies, as I'm not on the lists).

I bumped into a problem which bisecting led to this same commit. And,
it turns out the problem is the same one pointed out above, i.e. the
recursive inlining report. The following patch fixes the issue.
