Hi,
my multi_index use case: * The container contains not objects themselves, but pointers (shared_ptr-s). * The objects are noncopyable - they are created by a factory and only smart pointers are copied between clients. * The container has 2 indexes. Indexes are built on const_mem_fn extractor. One of the indexes uses a function from a base class.
It seems that in 1.34 problem with using member function from a base class is supposed to be solved, but it causes a regression that you cannot have pointers to noncopyable objects in the container. Is this a known issue?
My compiler is MSVC 7.1/Intel Compiler 9.0. Here is a code snippet to demonstrate the problem. This code compiles well with boost 1.33.1, but fails to compile with RC 1.34. If you uncomment the second index, it won't compile neither with 1.33 nor with 1.34.
Hello again, Alexei, after the illuminating discussion with Mr. Maddock I've realized that I'm using is_convertible in a suboptimal fashion with respect to the kind of convertibility I want to detect. Could you please run your snippet using the attached version of boost/multi_index/mem_fun.hpp? If I haven't done some mistake, this should make your code work, even with the second index uncommented.
