I will admit I do not as yet understand why this error happens sometimes. You will see several tickets about this in trac with minimal searching, going back over the past 2 or 3 years. Peter has this issue all the time on his PowerPC. I had never noticed this issue, until a recent build of gcc7 on a Tiger i386 system, when I got this too. I am not certain if this is due to different dwarf debug symbols, but I can remember at one point we though this might be the issue. I have wondered if the “compare” program was erring when doing the comparison. Sometimes, for no particular reason, just restarting the gcc build again, without cleaning, can work. There is a way to turn off the multiple-building-comparison feature, and just going straight to one bootstrap (stage1) and one final (stage2) compiler, and skip the stage3 comparison. I don’t think you’d be taking much of a risk doing this — gcc is well-vetted. Best, Ken
