https://svn.boost.org/trac10/ticket/13227 <p> Hi, </p> <p> MSVC falsely report a missing virtual destructor inside exception.hpp Would it be possible to add a "pragma warning (disable:4265)" in this file ? This will *not* happen with the default settings of Visual Studio : it happens when trying to raise the warning level (/we4265 : treat "misssing virtual destructor" as an error) </p> <p> Steps to reproduce the problem : </p> <ul><li>Compile the following program: <pre class="wiki"> #include &lt;string&gt; #include &lt;iostream&gt; #include &lt;boost/optional/optional.hpp&gt; int main(int argc, char **argv) { boost::optional&lt;std::string&gt; name; if (argc &gt; 1) name.reset(argv[1]); if (name.is_initialized()) std::cout &lt;&lt; "Hello, " &lt;&lt; name.get() &lt;&lt; "\n"; else std::cout &lt;&lt; "Hello, world \n"; return 0; } </pre></li></ul><ul><li>With the following command line : <pre class="wiki"> cl hello.cpp /Iboost_1_64_0 /EHa /W3 /we4265 </pre></li></ul><p> outputs </p> <pre class="wiki"> c:\tmp&gt;cl hello.cpp /Iboost_1_64_0 /EHa /W3 /we4265 Microsoft (R) C/C++ Optimizing Compiler Version 19.00.24215.1 for x86 Copyright (C) Microsoft Corporation.
