/*
 * This test allocate and free some resources in order to be able to detect
 * leaks using a leak detector.
 *
 * To use with GCC/Clang address sanitizer you can set or add these options:
 *   CFLAGS="-fsanitize=address -fno-omit-frame-pointer"
 *   LDFLAGS="-fsanitize=address -lasan"
 * Note that early GCC address sanitizer don't have a leak detector.
 *
 * To use Valgrind you can run the test with:
 *   valgrind --tool=memcheck --leak-check=full ./test-leaks
 * For cleaner output you should suppress GLib checks with glib.supp file.
