Compiling the following with "dmd -c a.d" results in a failure of the last 
static assertion. Removing the actual dependency of b on a by commenting out 
the declaration of J lets the assertion pass.

This bug is the supposed cause for loads of bogus error messages referring to 
"startsWith" or "Appender". I was sure that the issue was already reported, but 
didn't find anything useful, except for some possibly related bugs that have no 
reduced test case.

This is a regression introduced in DMD 2.061.

a.d
---
import b;
interface I {}
---

b.d
---
import a;

interface J : I {} // remove this line to make it work

static assert(is(typeof({ import c; }))); // OK
pragma(msg, B!().result); // just instantiates the template

template B() {
    static assert(is(typeof({ import c; }))); // FAILS
    enum result = "WORKS";
}

Oh and of course a "c" module is also needed:

c.d
---
// empty
