memory leaks #40
Description
When using address sanitizer (e.g., export CFLAGS="-fsanitize=address -fno-omit-frame-pointer -g -Wall" && export ASAN_OPTIONS="abort_on_error=1" && export LDFLAGS="-fsanitize=address"), make check fails with various memory leaks.
At least one of them (related to bulk buffer on read operations) might be significant.
