Again, that would happen in the sources you pick up from me, and per part1 https://github.com/wch/r-source/commit/d60792d3f404cc970ab33ebee1d4481a770ec15c part2 https://github.com/wch/r-source/commit/05046138c6fa9b40b9676f6b67498d74281d5030 it only affects gfortran >= 7, and my Debian stable fileserver shows gcc still the default so no rush. | > In principle I think all Fortran BLAS/LAPACK implementations (refblas | > and ATLAS) packaged for buster should be recompiled with | > -fno-optimize-sibling-calls (they may be fine in case they were compiled | > with older version of gfortran-8, but then the next rebuild will cause | > trouble): Dirk, any chance you could get the package maintainers to make | > these changes? | | It seems to me this is of relevance for for Sébastien (Ccing), or more | generally for debian-science. Not really. I do not think anybody concluded our LAPACK/BLAS needed to be recompiled. The discussion about this has been going on for a few weeks and is now also between gcc/gfortran upstream and the lapack folks. See Tomas's posts on (IIRC) r-devel. So in short, things are moving, and in the right direction. Also worth recalling that the _initial findings_ were and still are about a gcc / gfortran version _not even in Debian unstable yet_ (but the folks in Fedora once again jumped the gun and they now have that problem with gfortran 9).
