Shouldn't the range be alive until the end of the loop?


It should. Which compiler version are you using? I remember 
there recently was a bugfix for a very similar bug, it might 
not have been released yet. Can you please either test with DMD 
from Git (you'd need to build it yourself), or provide a 
minimal testcase so I can test it for you?


I see Lionello already provided one. The bug is still there in 
DMD master.

Looks like a bug. I can repro it as well.
