Can you provide an example of use that shows the problem/error?
Here's an excerpt from the example given in one of my previous replies to this post:
typedef cycle_iterator<base_it_,size_> it_; it_ it(boost::begin(vec),boost::end(vec),0); it_ it2; it2 = it;
/Developer/SDKs/MacOSX10.5.sdk/usr/include/c++/4.0.0/debug/safe_iterator.h:162:
error: attempt to copy from a singular iterator.
Interesting. This example, which I think is equivalent to yours, compiles fine with gcc-4.4.1: (I'm afraid I don't know what the above error means) #include "cycle_iterator.hpp" #include <vector> int main() { std::vector<int> v; typedef boost::cycle_iterator<std::vector<int>::iterator,size_t> it_; it_ it (v.begin(), v.end(), 0); it_ it2; it2 = it; }
