Bug 7741 – getHash inconsistent for const(char)[] vs. char[] and string

Code: char[] a = "abc".dup; const(char)[] b = "abc"; string c = "abc"; writeln(typeid(a).getHash(&a)); // 12914 writeln(typeid(b).getHash(&b)); // 8503969683799911018 writeln(typeid(c).getHash(&c)); // 12914 It appears that char[] and string (==immutable(char)[]) have getHash implemented in rt.typeinfo.ti_Ad.TypeInfo_Aa, which has its own hashing algorithm, whereas const(char)[] just uses object.TypeInfo_Array.getHash, which calls rt.util.hash.hashOf.

Fixed in git HEAD.
