There is a test that not included in CI was broken:

rust-rocksdb/librocksdb-sys/Makefile

Lines 8 to 17 in 873baa2

	test:
	cargo build
	rm -rf tmp-test-memory-leak
	gcc -g -I rocksdb/include/ -I . \
	-L $$(find . -name "librocksdb.a" -exec dirname {} \; | head -1) \
	-o tmp-test-memory-leak \
	tests/memory/rocksdb_options_load_from_file.c \
	-lrocksdb -lpthread -ldl -lm -lstdc++ \
	&& valgrind --tool=memcheck --leak-check=full ./tmp-test-memory-leak \
	&& rm tmp-test-memory-leak

This test was used to check if there is any memory leak. (Ref: #18 (comment))
