Hi all,
Yesterday I discovered what seems to me like a memory leak in png() so I'm
reporting it in case that is helpful. Here is a small reproducible example:
R -d "valgrind --tool=memcheck --track-origins=yes --leak-check=full"
--vanilla -e "png(filename='p.png'); plot(1:10); dev.off()"

Thus, `1 + numeric()` returns `numeric(0)`. However, I don't find this
very intuitive because
