Memory leaks

[ablaette]

When I run sanitizers on RcppCWB with rocker/r-devel-ubsan-clang, this is an example of what I see:

Indirect leak of 2 byte(s) in 1 object(s) allocated from:

This is the summary:

Could not reconstruct what I did in march. As I could not install valgrind on my M1 mac, I ran things in a rocker-Docker container (rocker/r-devel-ubsan-clang) on an Intel Mac. First I ran R CMD check, cd'd into the check dir, then:

R -d "valgrind --tool=memcheck --leak-check=full --show-leak-kinds=all --track-origins=yes -s" -f RcppCWB-Ex.R

This yields the most extensive error report. I do not see anything serious, but obviously there are memory leaks.
