Some bug in xcode's non gnu arm assembler.

Question

this is a very lite demo, taked from my complete hook project.
.syntax unified
.macro .donothing
.text
.private_extern $0
.globl $0
.align 2
.arm
$0:
    movw    r0, :lower16:2f-(1f+8))
    movt    r0, :upper16:2f-(1f+8))
1:
    add     r0, pc, r0
    blx     lr
.cstring
2:
    .asciz $1
.endm
.donothing _getstr, "He llo wor ld !\n"
I added the .s file into xcode, and call it from main.cpp like this
#include <stdio.h>
extern "C" char* getstr();
int main(int argc, char* argv[]) {
    fprintf(stderr, "%s", getstr());
    return 0;
only "Helloworld!\n" printed in xcode's lldb console. all space in $1 removed during macro expanding. surely *.o file already have striped version for my string (with otool).
I am using XCode 4.3.3, I think it's totally a bug, not a design.
because the same x64 version working fine.
.macro .donothing
.text
.private_extern $0
.globl $0
.align 2
$0:
    leaq     1f(%rip), %rax
    ret
.cstring
1:
    .asciz $1
.endm
.donothing _getstr, "He llo wor ld !\n"
back to the arm clang/llvm as, I found instruction like
adr r12, label
just let assembler (libexec/arm/as) crash without any output.
ldr r12, =0x8
can crash assemberl sometimes too.

Aperture fails to function correctly with an explicitly supported camera, running on an explicitly supported OS and an explicitly supported machine. How is that not a bug? And why is calling a bug a bug off-putting? There is nothing strange about bugs, practically all software has plenty of them.
Frankly, I found Frank's first comment, with the immediate dismissal (without asking any questions) and the silly remark about zebras, quite arrogant. But enough of this, I have no desire for discussions of matters of no consequence with strangers on the web.
To get back on topic, I tried Canon's EOS Utility on the same machine, and it imports all files without problems. This is a quite strong further evidence that the problem is somewhere in Aperture's software stack (and Image Capture's). I suggest that anyone with the same problem use EOS Utility to grab the files until the bug is fixed. I'll try to contact the Aperture devs in the way Terence Devlin suggested.
