The first jump to a specific label was marked as jump to absolute position -4. This value was stored in the assembly as a branch to a offset (-4 - (instruction offset + 8)). The offset is only 24 bit long on ARM. Thus instruction offsets higher than 2^23 - 12 would overflow the offset. Fix by denoting the first jump to a label by storing the jump instruction location as the target. This will result in offset of -8, which of course always fits in the branch instruction.
