It is indeed a bug. It's caused by the AA implementation receiving a
static char array when it's expecting a string (immutable(char)[])
according to the declared key type of the AA.

Filed a bug for this:

The compiler should either reject indexing an AA with a char[n], or it
should automatically slice the char[n] so that the AA implementation
gets the correct type in the key argument.
