DMD 0.138 on Windows also accepts it without complaint.

What tools and OS did you use and exactly when did DMD crash?

Removing the ellipses makes it operate fine.


Additionally, this variation:

class Bar
{
        this(int i, ...) {}
}

class Foo
{
        void opAdd (Bar b) {}
}

void main()
{
        auto f = new Foo;
        f + new Bar(1, 0); // error here
}

produces this error:

template.d: constructor template.Bar.this (int,...) does not match argument 
types (TypeInfo[],int,int)
cannot implicitly convert expression (_arguments_i) of type TypeInfo[] to 
int

I can't reproduce this with WindowsXP and dmd-0.137.
Are you sure that this is DMD's fault and not a "virus scanner" or
some other "security" tool?

Some of those tests crash if "-fPIC" is used:

Perhaps ... but then why would it work when the ellipses are removed? It's a 
mystery.
