           Summary: dmd exits with -4 on dub release (not sure what causes
                    error, but have minimal repro code)

Full "project" including dub.json

Having a file with this piece of code in sources crashes compiler with -4 exit code. Reduced with dustmite.

Names and imports don't matter (import std; crashes also).

------------------------------------------------
import std.math: sin, acos;

struct ErrorStruct {
    float[] data;

    this(float[] vals...) { data = [vals[0]]; }

    ErrorStruct doMath(double a) {
        double d;

        float hth = acos(d);
        float ra = sin(-a * hth);
        float rb = a * hth;
        return ErrorStruct(ra + rb);
    }
}
------------------------------------------------

Also I'm sorry about issue name but I genuenly have no idea why it does that here
