There is a lot of difference between those two. In particular, it looks like the problem you are seeing is coming from the background writer, which is not running during initdb. I think the next step would be for you to compile in debug mode with -O0, and attach to the bgwriter process with gdb, and step through it. Then, you can see the exact path which causes the bgwriter to exit, and that will give you a better idea where the problem is.
