--- Comment #10 from PeteVine <tulipawn at gmail dot com> --- Yeah, I began suspecting as much yesterday so I left it running overnight on ARM. It managed to get to stage comparison but failed due to many differences. But not before I'd got impatient in the morning and did a start/stop switching the linker back to gold, probably my fault :)
