gcc-4.7 shows the same amount of errors, while gcc-4.6 only shows:

Problem is because the input is invalid . We just end up generating 

ldrex r0, [r1, #-24] . 


    asm volatile(
        "movw %1, #1\n\t"
        "ldrex %2, %0\n\t"
        "cmp %3, %2\n\t"
        "bne.n 0f\n\t"
        "strex %1, %4, %0\n\t"
        "0:"
        : "+m"(*location), "=&r"(result), "=&r"(tmp)
        : "r"(expected), "r"(newValue)
        : "memory");


Eh - you can't use m for a constraint to an address in ldrex . Try "+Q" instead.
