Does the problem come from a new version of Mac, or because you use a 32-bit version of R (which I thought had been deprecated)?

[barracuda156]

@privefl Thank you for responding. The last macOS to support PPC is 10.6, which is what I test.

R works perfectly fine on 32-bit, and majority of packages work and pass all tests. I am the maintainer for R packages in Macports, so this is not just for me personally: I wanna fix this for all users.

All the tests on CRAN pass (which does not test 32 bits anymore it seems). I have no way to test for this architecture. So, unless you have a solution for this, this probably won't be fixed. The thing is that I use double precision numbers for this format, so I'm not sure how this would work on a 32-bit architecture.

All the tests on CRAN pass (which does not test 32 bits anymore it seems). I have no way to test for this architecture.

Maybe on Linux or BSD? Or even Windows? Bitness issues are rarely macOS-specific (some are, like 128-bit floating point format).

The thing is that I use double precision numbers for this format, so I'm not sure how this would work on a 32-bit architecture.

That is, 64-bit? That should work, provided that endianness is used correctly.

Just as an update on the status, 0.7.3 still has the issue:

[privefl]

Is this only this test with old versions of SFBMs that fails? That should not matter unless you stored some SFBM from a long time ago.

[barracuda156]

@privefl From the output looks like yes, everything else passes.

Is this a problem you encounter yourself?
