Should I
(1) reopen pr59749,
(2) open a new pr,
(3) let you handle the problem without further fuss?
For (1) or (2) do you need a preprocessed file?
I'm certainly not seeing 59747 failing anymore:

I don't have a darwin box so I'd probably need the .i & .s files so that
I could poke at it a bit with a cross compiler.
I think reopening 59749 would be appropriate.
