I think one difference is big endian (ppc64 client on jenkins) vs little endian on my client.

[Andreas Dilger]

I thought we build every patch on Power, how is your build different from what is done by Jenkins?

[James A Simmons]

Yes I saw this some time ago but haven't got around to it. Its the return of PRi64 handling.
