I tried something like this:

foreach(e; scoped!SomeRangeType(args)) {
}

And my program segment faults. But this works:

{
     auto x = scoped!SomeRangeType(args);
     foreach(e; x) {
     }
}

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.
