void _mixin() {
    writefln( "" );
}
void main() {
    mixin( _mixin );
}
//Assertion failure: '!dim || (parameters && (parameters->dim == dim))' on line
140 in file 'interpret.c'
With both D1.056 and D2.040

Reduced test case for test suite:
-----
void badvariadic(...) {}
static assert(!is(typeof(mixin(badvariadic()))));
---

PATCH: interpret.c line 118. The check for C-style variadics failed in the case where there were no non-variadic parameters.

    TypeFunction *tf = (TypeFunction *)tb;
    Type *tret = tf->next->toBasetype();
-    if (tf->varargs && arguments && parameters && arguments->dim !=
parameters->dim)
+    if (tf->varargs && arguments && (parameters && arguments->dim !=
parameters->dim) || (!parameters && arguments->dim))
    {    cantInterpret = 1;
    error("C-style variadic functions are not yet implemented in CTFE");
    return NULL;
    }

Oops, there's a missing parentheses. Should be:

if (tf->varargs && arguments && ((parameters && arguments->dim !=
parameters->dim) || (!parameters && arguments->dim)))
