Hi
I was able to reproduce this in Ubuntu 20.04 on i7-2600 with the
Rscript -e "example(solve)"
test case. Rebuilding with
export DEB_LDFLAGS_MAINT_STRIP="-Wl,-Bsymbolic-functions"
in debian/rules solved it for me.

I confirm that a no-change rebuild had no effect.
I suspect this is the same problem that was discovered in LP: #1860601
[1], but I was unable to reproduce it locally.
I'll take care of fixing this in Ubuntu Groovy and SRU for Ubuntu Focal.
Could we get this fixed in Debian? At worst, it should be a no-op in
Debian, and should someone try rebuilding locally with -Bsymbolic-
functions they won't fall into this trap.
Regards
Graham
