test.d:
-----
module test;

import foo;

enum E { a, }
-----

foo.d:
-----
module foo;

import test;

string[E] es;
-----

2.063
$ dmd -c test.d
> 

2.064: 
$ dmd -c test.d
> assert mtype.c(7524) sym->memtype

It fails if the enum is used as the hash key type, but it works if it's used as
the hash value type.
