This seems to have been fix as I cannot reproduce the example provided by John
Colvin.

Attributing `opEquals` with `nothrow` resolves the linker error:

struct S
{
P payload;
alias payload this;
}

struct P
{
auto opEquals(T)(T other) const nothrow  //*** Needs nothrow ***/
{
static assert(is(typeof(performOp!(S[], T;
return const(S[]).init == other;
}
}

bool performOp(T, A)(T value, A arg)
{
return value == arg;
}

Here is a standalone file that demonstrates what I think is a symptom of the
same bug:

% cat oops.d
struct JSONValue
{
TaggedAlgebraic payload;
alias payload this;
}

struct TaggedAlgebraic
{
auto opEquals(T)(T other) const
{
static assert(is(typeof(performOp!(JSONValue[], T;
return const(JSONValue[]).init == other;
}
}

bool performOp(T, A)(T value, A arg)
{
return value == arg;
}

% dmd oops.d
