--- Comment #1 from Basile-z <b2.temp@gmx.com> ---
The loop happens in

  dmd.optimize.Expression.Expression_optimize(Expression e, int result, bool
keepLvalue)

But the background problem is that template parameter type deduction gives `ubyte ` instead of `void`. As a consequence the protections against infinite recursion when the optimizer visit a CastExpression don't work.

For example by rewriting the call in the test case this way

  (void[1]).init.front!void;

that works but

  (void[1]).init.front!ubyte;

loops...
