The program

 int main() { return 0; }

compiled with

 clang -S s.c -o s_clang.s -g -target i686-pc-mingw32

produces empty .debug_aranges:

    .section    .debug_aranges,"rn"
    .section    .debug_macinfo,"rn"

compiled with 

  gcc -S s.c -g -o s_gcc.s

produces correct .debug_aranges:

    .section    .debug_aranges,"dr"
    .long    0x1c
    .word    0x2
    .secrel32    Ldebug_info0
    .byte    0x4
    .byte    0
    .word    0
    .word    0
    .long    Ltext0
    .long    Letext0-Ltext0
