I did not read that in the posts and on dmd 2.057/win32 only an out of memory was thrown.

It is a bug in your code:

-                ForEachIndex!(N+1, L).result;
+                ForEachIndex!(N+1, L[1..$]).result;

The diagnostic DMD spits out is quite bad.

Wow.

In my defense, the original code is right; apparently dustmite did this to the reduced case.

I know I had that stuff working last summer.

Thanks for the analysis.
