Problem found in dmd 2.042. This doesn't compile:

int foo() {
    int[int] aa;
    aa[1] = 2;
    return 0;
}
enum _ = foo();
void main() {}


Giving the errors:

test.d(3): Error: Cannot index null array aa
test.d(6): Error: cannot evaluate foo() at compile time
test.d(6): Error: cannot evaluate foo() at compile time

It seems that when I use an 2D AA this problem still occurs. This is the code I used:


enum auto i = test();

int test()
{
    string[][string] s;
    s["a"] ~= "anything";

    return 6;
}


It gives me almost the same error (on Linux x64) the OP had:

Error: cannot index null array s

Your test case is completely different to the original bug, it is a bug in ~=.

Please do not reopen ancient bugs. The *only* time you should open a bug which was listed as fixed in a previous changelog, is if you find that the test cases in bug weren't actually fixed in that release.

Moved to bug 9023.
