It looks like you can't have an associative array on strings?

int main()
{
  char[char[]] a;
  a["aa"] = "bb";
  return( 0 );
}

gives an error of:

z.d(4): cannot implicitly convert char[2] to char

If this were:

  int[char[]] a;
  a["aa"] = 1;

it works okay.

You should get the desired result if you declare it like so:
char[] [char[]] a;

That's what was happening. The compiler thought you were trying to assign "aa" (char[2]) to a char[1] variable.

No, it's not a bug, you would have an array of chars, not of strings.  It should be written as char[][char[]] a.
