Might be best to talk to the maintainer(s) of liblapack3, who may or may not
be conversant in R so a reproducible example in just C may help.
I just checked https://packages.debian.org/search?keywords=lapack and 3.5.0-4
is the most recent version.
In the meantime you can of course also try switching to Atlas or OpenBLAS and
see how your matrix does there.
