And this is the assembler code when executing -S -O1 (cf. below), while for the
-O2
version the compilation leads to an assembler file showing only the .text line:
        .text
        .globl _hoo

        subq    $40, %rsp

        movl    $32, %edx
        call    ___strcpy_chk
        addq    $40, %rsp
