Dear R people, Tests of nlme on aarch64 seem to fail:
--8<---------------cut here---------------start------------->8--- Running specific tests for package ‘nlme’ Running ‘anova.gls.R’ Error: running the tests in ‘anova.gls.R’ failed Tests failed, dumping logs. --- ./nlme-tests/anova.gls.Rout.fail ---------------------------------------- R version 4.5.2 (2025-10-31) -- "[Not] Part in a Rumble" Copyright (C) 2025 The R Foundation for Statistical Computing Platform: aarch64-unknown-linux-gnu R is free software and comes with ABSOLUTELY NO WARRANTY.

Question 1 : Is it known? I don't have other aarch64 boards at hand (this one is rk3399 based). Question 2 : If I build nlme with this flag and other packages without it, should I expect problems? I am asking because I am trying to upgrade the package definition in my gnu/linux distribution (Guix) in order to support aarch64 (tests being required to pass). Thank you!
