Description Stefan Frijters 2015-12-14 08:25:13 UTC 
Using the 0.8.3 dub version of std.experimental.ndslice, dmd 2.069.1 segfaults on the following reduced code:

import std.experimental.ndslice;

void main() {
	Slice!(3, double*) force = new double[60].sliced(3, 4, 5);
	// Wrong foreach params. dmd failed with exit code -11.
	foreach(p, e; force)
	{
	}
}

Further reduced:

% cat test.d
struct Slice
{
    auto front()() {}
}

void foo()
{
    Slice force;
    foreach(p, e; force){}
}

% dmd test.d
