digitalmars.D - Xcode 8 and DMD

Having installed Xcode 8 recently, I have discovered that the linker and 
DMD do not play nice together. See my bug report here:

https://issues.dlang.org/show_bug.cgi?id=17289

I'm a bit concerned that the misalignment of pointers might cause 
performance degradation, so I'm going to switch to LDC for now, but this 
seems like a serious issue, but seems to be limited to certain 
circumstances, so it might be easy to find.

It seems to have occurred around DMD 2.069. Anyone can figure this out? 
I'd be curious if DMD generated code performance gets better on Mac.
