Thanks.

However there is slight problem with this. Instrumentation is missing without
-fsanitize-address-use-after-scope option.
IMO, it should depend only on --param asan-stack=1.

So the following doesn't produce any output:
gcc -fsanitize=address -fno-sanitize-address-use-after-scope -O2 asan_test.c &&
./a.out

Can we fix this?
