All the linker errors originate from zio.d but zio.d has its 
unittests disabled so how come this fails to link?

And how come

     dub build --unittest

passes

when

     dub test

doesn't?

I'm sitting on Ubuntu 20.04 x64.

zio.d is not the source of the problem. Something else is.

The common denominator seems to be that the builtins xopEqual and 
xopCmp aren't defined upon linking. These seem to be generated by 
dmd. Can anybody explain what's going on here?

I'm trying to reduce it through

     dustmite phobos-next "dub test 2>&1 | grep -F 
'_D6object10_xopEqualsFMxPvMxQeZb'"

Is this the best way to use dustmite in this case?

Was reduced to rational.d with content


module nxt.rational;

Rational!(I1) rational(I1, I2)(I1 , I2)
{
     return typeof(return)();
}

struct Rational(Int)
{
     bool opEquals(Rhs)(Rhs _) {}
}

 nogc unittest
{
     auto _ = rational(1, 2);
}


When I remove

     bool opEquals(Rhs)(Rhs _) {}

error goes away. Seems like a bug to me.
