memory leak

[levBagryansky]

I started besm666_page_pool_tests with sanitaizers adding to test/memory/CMakeLists the following:

target_compile_options(besm666_page_pool_tests PUBLIC -fsanitize=address -g)
set_target_properties(besm666_page_pool_tests PROPERTIES LINK_FLAGS "-fsanitize=address")

and get the error below:
