Details:
Something is seriously broken in NSMutableDictionary with respect to
GSUnicodeInlineString keys, as seen in this transcript from gdb. As you can
see, the dictionary wasn't able to retrieve the object when the key was that
type of string. This is using the latest tip of the trunk (r29095) but I think
it has been broken for a while. This issue didn't exist back in r28259 or so.
(gdb) p [aKey hash]
$12 = 111128
(gdb) p [@"cat" hash]
$13 = 111128
(gdb) p [aKey isEqual:@"cat"]
$14 = 1 '\001'
(gdb) p [aKey isEqualToString:@"cat"]
$15 = 1 '\001'
(gdb) po theDict
{cat = "(species:\"feline\")"; "first name" = Mike; }
(gdb) p [theDict objectForKey:@"cat"]
$16 = (struct objc_object *) 0x83f3ef0
(gdb) p [theDict objectForKey:aKey]
$17 = (struct objc_object *) 0x0
(gdb) po [@"cat" class]
GSCBufferString
(gdb) po [aKey class]
GSUnicodeInlineString
(gdb) po [theDict class]
GSMutableDictionary
(gdb)
