Using AddressSanitizer to find memory errors in R packages requires the
R installation to be built with AddressSanitizer, too.

I found it useful to build the package with -g (and maybe -Og), then
run the checks using `R -d valgrind CMD check ...`. Sometimes the
errors found by Valgrind are different from errors found by
AddressSanitizer, though (not to mention the differences in hardware).
