[R-pkg-devel] CRAN checks failing for ATLAS

Hi, I was notified by the CRAN maintainers that checks for my package are failing: https://cran.r-project.org/web/checks/check_results_usl.html I don?t understand what?s going on here. All regular checks show the OK status. Only the linked ATLAS check fails. What is so special about this check?
It's the same check, but using ATLAS as the algebra back-end instead of BLAS.
The check seems to be running on x86_64-pc-linux-gnu (64-bit) and use the R development version (2020-02-20 r77833). The regular check "r-devel-linux-x86_64-debian-gcc" runs on the same platform and a later version but doesn?t fail. Any hints what is causing the failures?
It seems that you are checking exact output values in your tests, and changing the library changes the computed coefficients. This is generally a bad idea, precisely as this issue demonstrates. Checking ranges or numbers with some tolerance is much better, but then you cannot rely on .Rout. I?aki
Regards, Stefan
