Comment (by anonymous):

 I see, I missed that part in the docs. Thanks for being patient. boost has
 wrappers to make type traits and static assert work on supported
 compilers:

 http://www.boost.org/doc/libs/1_52_0/libs/type_traits/doc/html/boost_typetraits/reference/is_pod.html

 What about the algorithm requires POD? It seems like it is doing
 everything that would be needed to support non-POD types. And indeed the
 destructor is called for all but 1 of the items, which sticks around until
 the queue goes out of scope at which point it too is destructed. Which is
 to say the program is valgrind clean:

 {{{
 ==38928== HEAP SUMMARY:
 ==38928==     in use at exit: 0 bytes in 0 blocks
 ==38928==   total heap usage: 147 allocs, 147 frees, 9,088 bytes allocated
 ==38928==
 ==38928== All heap blocks were freed -- no leaks are possible
 }}}

 Also, if only trivial POD types are supported, why even call the
 destructor? trivial destructors don't do anything.
