By the way, note that -Bsymbolic != -Bsymbolic-functions From dpgk's changelog, it seems Ubuntu have linking with -Bsymbolic-functions as default since about 2008. codesearch.debian.net only shows about 62 source packages (of the 10s of thousands in Debian) where this needs to be overridden. It seems overriding it in openblas only became necessary since the restructuring in 0.3.7+ds-2, so no versions prior to Focal should be affected. Regards Graham
