At a guess, it's some floating point rounding issue or similar, and a failure of the test itself rather than the binary. subsurface actually avoids using floating point for most things (most data being kept as integers in well-defined formats - like "depth in mm" etc). But things like the deco algorithms do use floating point, so I could see that causing issues for things like calculated profiles etc. The other failure mode we've seen is just silly locale differences - we've had bugs like printing out floating point numbers using ',' vs '.' etc. Anyway, regardless of what the cause of the failure is, what you can do is something like this: Rerun just that test: cd build/tests ./TestProfile and you should now have the two output files in that directory: exportprofile.csv and exportprofileVPMB.csv. The tests then compare that to the expected end results that are in the 'dives' directory in the source tree, so this *should* give an empty diff diff -u ../../dives/exportprofilereferenceVPMB.csv exportprofileVPMB.csv but clearly that part fails. And what would be interesting to see is the difference between the reference file and the generated file. Don't send the whole diff to the mailing list in case it's "every line differs in one character" kind of thing. But if you can pinpoint more precisely what the difference is, we can figure it out, I'm sure. I don't have a 32-bit environment any more (and it might not be about x86-64 vs i386: as mentioned it could be something like an unusual locale thing too, and might be specific to void for some odd reason).
