--- Comment #1 from ag0aep6g <ag0aep6g at gmail.com> ---
The string data is getting misaligned. wcslen assumes properly aligned data.
testabcd.d can be reduced to this:

----
alias wchar_t = dchar;
const(wchar_t)* name = "abcd";
void test()
{
    assert((cast(size_t) name) % wchar_t.sizeof == 0); /* Fails. Should pass.
*/
}
----
