clang不喜欢boost :: signals2？

我整天都在使用Boost :: Signals2库从代码部分中获取编译器错误.我已经将我想要做的事情简化为一个最小的例子:

#include 

int foo();

struct first_nonzero
{
    using result_type = int;

    template 
    result_type operator()(It first, It last) const
    {
    while(first != last)
    {
        if(*first != 0)
        {
            return *first;
        }
    }
    return 0;
    }
};

int foo()
{
    using signal = boost::signals2::signal;
    signal s;
    return s();
}

当我尝试编译此代码段时

clang -o foo.o -c foo.cpp -std=c++11 -Weverything -Wno-c++98-compat

我得到一个模板推导错误,似乎来自信号库本身:

过了一段时间后,我决定尝试使用不同的编译器疯狂的想法,令我惊讶的是,如果我编译相同的代码片段

g++ -o foo.o -c foo.cpp -std=c++11 -Wall -Wextra -pedantic

我没有错.我正在Debian clang version 3.2-7ubuntu1 (tags/RELEASE_32/final) (based on LLVM 3.2)和g++ (Ubuntu/Linaro 4.8.1-10ubuntu9) 4.8.1; 提升图书馆1.54.

由于项目限制,我不可能使用不同的编译器.有没有办法坚持clang并仍然使用boost :: signals2库？
