With this change the output is ``` r1 = 2569 *(u16 *)(r10 - 4) = r1 r1 = 134678021 *(u32 *)(r10 - 8) = r1 ``` i.e. the 0x0A09 has been split out from the 0x8070605. I have no idea yet why this change would do that. Also, there is actually a memset on the next line, which seem to be zeroing the memory *after* the alloca'd pointer (which I think is UB?). Removing it doesn't seem to affect the output, but maybe something weird is going on.
