  1. POlibc++ Error in instantiation of exception specification for vector and string compiling simple code
    text
    copied!<p>I get errors when compiling this simple code and if I remove the noexcept I don't get the error:</p> <pre><code>#include&lt;vector&gt; #include&lt;string&gt; class Foo { public: protected: Foo(Foo&amp;&amp;) noexcept = default; Foo&amp; operator=(Foo&amp;&amp;) noexcept = default; Foo() { } private: std::vector&lt;std::string&gt; vectorFoo_; }; </code></pre> <p>This is the errors I get, I understand it is in the instantiation of the exception specification, but I doubt the std::string is not nothrow move constructible,.. the first error make me think there is a bug. </p> <blockquote> <p>In file included from /Users/Mani/Development/Projects/flowOfLife/Graphics/Graphics/TestCompileError.cpp:1: In file included from /Users/Mani/Development/Projects/flowOfLife/Graphics/Graphics/TestCompileError.h:4: /usr/local/bin/../lib/c++/v1/vector:575:67: error: no member named 'value' in 'std::__1::is_nothrow_move_constructible, std::__1::allocator > > >' <em>NOEXCEPT</em>(is_nothrow_move_constructible::value);

What am-I doing wrong?</p> <p>Thanks</p> <p><strong>Update</strong> <a href="http://coliru.stacked-crooked.com/a/ab2fb522c4982c72" rel="nofollow">The error on Coliru</a>. It seam that if I don't specify libc++ and instead use stdlibc++ it compiles. It is starting to look alot like a bug in libc++.</p>
