           Summary: ICE on const declaration
           Product: D
           Version: 2.030
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD

Try compiling following snippet:

module sound;

import std.math;

struct Sound
{
    float time;
    float delegate(float) func;

    this(float delegate(float) f, float t)
    {
        time = t;
        func = f;
    }

    Sound opAdd(const(Sound) other)
    {
        return Sound(
        (float t){
            return func(t) + other.func(t);
        }, fmax(time, other.time));
    }

    Sound opCat(const(Sound) other)
    {
        return Sound(
        (float t){
            if(t <= time)
                return func(t);
            return other.func(t - time);
        }, time + other.time);
    }

}


Gives the error message:

Shorter version.

struct Sound {
    int delegate(int) func;

    this(int delegate(int) f) {
    }

    Sound opAdd(const(Sound) other)
    {
        return Sound(
        (int t){
            return other.func(0);
        });
    }

}

This _might_ be a duplicate of 2560 or 2875.

Even shorter test case:

struct S {
    int q;
}

void foo(const(S) x) {
   int delegate(int t) bar = (int t){ return 1 + x.q; };
}
