(However Phobos is not using it, AFAIK.)

foreach does not use the range interface provided by std.array (that I know 
of). So there should be a bug reported on the current behavior of Access 
Violation.

I haven't checked on Windows, but there is no access violation in 
foreach (http://ideone.com/WSBRm), and there is no access violation in 
the range interface either (as of 2.052 it throws a 
std.utf.UtfException), so I don't know what bug you are talking about.
