--- Comment #1 from stefanos <ssofroni at cytanet dot com.cy> ---
I forgot to mention that if I try *directly* the following command

g++ -Wall -Wextra -Werror -Wpedantic -std=c++20 -g -g0
-fsanitize=address,undefined -D_GLIBCXX_DEBUG -fno-strict-aliasing -fwrapv -lm
-o tmp src/tmp.cpp

in place of Makefile, it triggers the memory leak.
