When the write barrier does several pointer writes under one write barrier flag check, the line numbers aren't really correct. The writes inside the write barrier have a confusing set of positions. The loads of the old values are given the line number of the corresponding store instruction, but the stores into the write buffer are given the line number of the first store. Instead, give them all line numbers corresponding to the store instruction. The writes at the merge point, which are the original writes and the only ones that happen when the barrier is off, are currently all given the line number of the first write. Instead give them their original line number.
