---------------------------------------------------------------------------
Key: STDCXX-334
URL: https://issues.apache.org/jira/browse/STDCXX-334
Project: C++ Standard Library
Issue Type: Bug
Components: 23. Containers
Affects Versions: 4.1.3
Environment: All
Reporter: Farid Zaripov
The program below fails:
---------------------------------------------
#include <list>
#include <string>
#include <cassert>
class Alloc : public std::allocator <char>
{
};
bool operator == (Alloc a1, Alloc a2)
{
return false;
}
bool operator != (Alloc a1, Alloc a2)
{
return true;
}
int main(int argc, char* argv[])
{
const char src [] = "source string";
const char dst [] = "destination string";
typedef std::list <char, Alloc> List;
Alloc a1;
Alloc a2;
assert (!(a1 == a2));
List src_lst (src, src + sizeof (src) - 1, a1);
List dst_lst (dst, dst + sizeof (dst) - 1, a2);
src_lst.swap (dst_lst);
assert (std::string (src_lst.begin (), src_lst.end ()) == dst);
assert (std::string (dst_lst.begin (), dst_lst.end ()) == src);
return 0;
}
---------------------------------------------
Assertion failed: std::string (dst_lst.begin (), dst_lst.end ()) == src, file
swap.cpp, line 37
