--- Comment #1 from Jon Degenhardt <jrdemail2000-dlang at yahoo.com> ---
This bug is triggered when a slice is taken entirely from the pad section at
the end of the range. Here's another variation:

---- issue_19042.d ----
import std.range;
import std.stdio;

void main(string[] args)
{
    auto r = [1, 2, 3, 4].padRight(0, 10);
    writeln("r[7 .. 9] : ", r[7 .. 9]);
}

---- Run -------

$ dmd issue_19042.d

$ ./issue_19042
core.exception.RangeError at INSTALLDIR/dmd2-2.084.0/osx/bin/../../src/phobos/std/range/package.d(12868):
