Could you set up your VMs to include those SSE instructions? I think that keeping VMs that "old" configured is a source of problems using pre-compiled binaries. The same way GDAL updates dependencies of compilers and other libraries to something more modern (but not too modern), those SSE instructions should be updated.
@Even knowing now that the "old" hardware is "virtually old", should we remove AVX2 compatibility from ubuntu-full-latest? I do not know how much is the performance impact. Cheers, Javier.
