------- Additional Comments From chris at bubblescope dot net 2005-08-18 17:26 -------
The following simple piece of code fails to compile.
#include <tr1/unordered_set>
int main(void)
{
std::tr1::unordered_set<int> i,j;
i = j;
}
The error is in fact in <tr1/hashtable>, and as all the unordered containers inherit from here, the bug
is in all of them.
There are two main reasons for this lack of compiling.
Firstly, hash_code_base::m_swap calls m_swap on various elements, most of which don't have a swap
member function. Changing these calls to swap fixes that, and does what the code should.
The second compilation error is on line 1275, hashtable::hashtable, where the member function
copy_code_from is called on a pointer. I'm not however sure what this function is supposed to do. If no
hashtable experts pop up, I intend to try to figure out how this functions works and how it should..
