See https://qa.debian.org/excuses.php?package=r-base : the pair of r-bioc-{iranges,s4vectors} is blocking the migration of r-base to testing. All of R, Rcpp, and these packages rebuilt to new versions recently so the toolchain should be consistent. Yet it looks like a plain segfault. Could one of you please take a look?
