Cannot emulate hash

[Bluna Ratimonkey]

Hi,
This code crash, it works fine with array, what could be wrong? I
can't backtrace for anything, I am using clang version 3.0 (trunk
137038)

NSHashTable* a = [NSHashTable new];

[a addObject:@"a"];
[a addObject:@"b"];
[a addObject:@"c"];

for (id obj in a)
{
}
