In correcting a minor bug in the optimx package, I submitted a new version today. The existing CRAN version (2024-12.2) has all CRAN checks OK, and to my knowledge no notifications of bugs. The new version has hit a FAIL with package phenofit revdep. Wanting to have output from a "working" system, I (re-)installed the CRAN version of optimx and ran R CMD check on phenofit, and also get the FAIL on one of its tests.
The failure is a solve error (singularity) in the called minimizer nlminb, so could be a result of some alteration in something like the matrix routines. I've also seen changes in tests due to use of M1 and similar processors, relaxed IEEE arithmetic being the cause. Such differences in outcome are not really a surprise, but can be a nuisance. My query is how to proceed to resolve this situation. Since my existing package -- which was supposedly OK back in December -- also throws the test failure in phenofit, I've no path to reverse changes in my code. It's also possible there's no error in phenofit, just a test case that now trips up when it did not prior to some external change. Still, some resolution is needed, and it would be good to avoid too much fuss.
