          Issue ID: 20905
           Summary: An alias inside a static if results in an undefined
                    identifier in some situations
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: kytodragon e.mail.de

This code:

struct Bar {
    Foo foo;  

static if (true) {
    alias my_type = ushort;

struct Foo {
    my_type index;  

results in this error:

test.d(11): Error: undefined identifier `my_type`

Removing Bar or moving Bar after the static if fixes it. This also happens, if
Bar is defined in another file and imported into the one with the static if.

Reproduced on Windows x64 with DMD 2.092.0 and LDC 1.21.0.
