Was it in the e-mail? As you quite correctly observed, many other
packages get the NOTE about shared library size.

It may be not exactly obvious, but the red link saying "LTO" on the
check page that points to
<https://www.stats.ox.ac.uk/pub/bdr/LTO/rar.out> is hiding a more
serious issue:

Modern C++ compilers are painfully pedantic about undefined behaviour
and can optimise away large sections of code if they think they have a
proof that your code causes it [*]. If you edit cpp11.cpp to provide the
correct declaration (#include the testthat header if possible), the
error should go away.
