I looked before I leaped in this case. I had time to do so because of the on-going build. While I do not have access right now, I do sometimes have access to a couple of 2-processor PowerMac G4s, but they are desktop machines. For all I know they might also have the tbr mis-match problems with th->th_offset_count in binputime as well. So at some point I may be able to test such a context. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
