This code can't possibly work

I was working on unit test today and realized I needed to do something I had done before in another unit test. I went reference it and maybe move it to a common function and discovered someone else had replaced it with something nonsensical.

I can't share the exact code obviously, but it essentially a for loop controlled by magic numbers that allocates an object into a global variable inside the loop then overwrites the pointer on the next iteration. I think it's a typedef of a shared pointer, so it might just barely not be a memory leak.

I wondered how this got through code review, so I looked and it was some > 1,000 line change by someone from another team. However, 2 people from my team gave this change approval.

What?
