This code:

--------------------------------------

string[char] aa = [
  'f': "foo",
  'b': "bar"
];

foreach (ch, str; aa) {
  writefln("[%s]: [%s]", ch, str);
}

--------------------------------------

Compiles fine but optlink complains:

test.obj(test)
 Error 42: Symbol Undefined
_D6object28__T16AssociativeArrayTaTAyaZ16AssociativeArray7opApplyMFMDFKaKAyaZiZi
--- errorlevel 1


while this compiles and links without problem:

--------------------------------------

string[string] aa = [
    "f": "foo",
    "b": "bar"
];

foreach (ch, str; aa) {
    writefln("[%s]: [%s]", ch, str);
}

--------------------------------------

Playing a bit with your test-case I have found this:


void main() {
    foreach (c, str; ['f': "foo"])
        c++;
}


Internal error: e2ir.c 4883

On 2.059, this gives:
PS E:\DigitalMars\dmd2\samples> rdmd  bug.d
bug.d(3): Error: non-constant expression ['f':"foo",'b':"bar"]

unless one defines:
enum string[char] aa = ['f': "foo",'b': "bar"];

(See issue 5279)
But with the above declaration, both description and comment 1 test cases run
fine.

Test case of description
PS E:\DigitalMars\dmd2\samples> rdmd  bug.d
[b]: [bar]
[f]: [foo]

So I suggest we close this issue while keeping issue 5279 open.
