           Summary: Hash initializer does not work
           Product: D
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: andrei metalanguage.com


The assertion in this program fails:

void main()
{
    int[string] stopWords = [ "abc"[]:1 ];
    assert("abc" in stopWords);
}

This is so bad I must in fact be doing something wrong...

Even more: this program:

import std.stdio;
void main()
{
        int[string] foo = ["aaa":1, "bbb":2];
        foo["ccc"] = 3;
        writeln(foo);
        writeln("aaa" in foo);
        writeln("ccc" in foo);
}

prints this:

        [aaa:1,bbb:2,ccc:3]
        0
        8F4FB4

when compiled using Windows DMD 2.018.

The docs says 'An AssocArrayLiteral cannot be used to statically initialize
anything', so the code should be rejected by the compiler. Changed keyword to
acepts-invalid.

BTW I've made the same mistake, see BUG 1727.

The last line is fine. "in" returns a pointer.

Notice that I'm using straight initialization, not static initialization.

In that case my comment on bug 1727 was valid, I'll repeat it here. The
following code compiles on both GDC and DMD, but DMD compiled code throws an
array bounds exception when executed.

test.d
------
import std.stdio;

void main() {
        int[char[]] aa =  ["aa":1, "bb":2, "cc":3]; // Fails later
        //int[char[]] aa; aa =  ["aa":1, "bb":2, "cc":3]; // Fails later 
        //int[char[]] aa; aa["aa"] = 1; aa["bb"] = 2; aa["cc"] = 3; // OK

        assert(aa.length == 3);
        assert(aa["aa"]==1); // DMD fails here. Error: ArrayBoundsError test(9)
        writefln(aa["aa"],aa["bb"],aa["cc"]); // On GDC output -> 123
}

I know. I posted this to maybe help to narrow down the issue. The printed array
contents are correct. The explicitly added key ("ccc") is found correctly. But,
at the same time, the key "aaa" is not found even though it seems to be present
in the AA.
