Why do we suddenly need to add markup for 1.33.1? This problem has been present for years.
well, indeed vc71 is affected as well, but I did not know about it. Did you?
I knew about the linker folding feature, but didn't know that the test wasn't failing only because folding wasn't on.
Is it mentioned somewhere in boost documentation?
No. This issue has never been reported as a practical problem; whether this is due to the fact that different functions of the same type sharing representation is rare, or due to the fact that mem_fn comparisons are rarely used, I don't know. Probably a combination of the two. The problem is not limited to member pointers. Try this simple test: #include <iostream> void f() { } void g() { } int main() { std::cout << (f == g) << std::endl; } This potentially affects function<>::contains and bind equality, but we don't have test cases for it. Yet.
