Bug 2333 – Hash initializer does not work

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. http://www.digitalmars.com/d/2.0/expression.html#AssocArrayLiteral 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 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.

Fixed dmd 2.020
