Did you apply my patch?  I got

        .globl  no_return_to_caller
        .type   no_return_to_caller, @function
no_return_to_caller:
.LFB0:
        .file 1 "pr38534-1.c"
        .loc 1 16 1 view -0
        .cfi_startproc
        .loc 1 17 3 view .LVU1
        .loc 1 18 3 view .LVU2
.LVL0:
        .loc 1 18 26 discriminator 1 view .LVU3
        .loc 1 16 1 is_stmt 0 view .LVU4
        subq    $24, %rsp
        .cfi_undefined 15
        .cfi_undefined 14
        .cfi_undefined 13
        .cfi_undefined 12
        .cfi_undefined 6
