Works with 2.064.2.
Fails with v2.065-devel-2b521dd.

---
cat > test.d << code
alias E = string;
void takeConst(const E[]) {}
E[] identity(E[] x) {return x;}
static assert({
    struct S
    {
        E[] a;
    }
    S s;

    takeConst(identity(s.a));
    version(A) s.a ~= [];
    else version(B)
    {
        s.a ~= "foo"; /* Error refers to this line (15), */
        E[] b = s.a[]; /* but only when this is here. */
    }

    return true;
}());
code
echo A; dmd -c -version=A test.d
echo B; dmd -c -version=B test.d
---
A
test.d(12): Error: Cannot interpret s.a ~= [] at compile time
test.d(20):        called from here: (*() => true)()
test.d(4):        while evaluating: static assert((*() => true)())
B
test.d(15): Error: array cast from string to string[] is not supported at
compile time
test.d(20):        called from here: (*() => true)()
test.d(4):        while evaluating: static assert((*() => true)())
