[Linux/gcc] 20.meta.unary.prop.cpp fails is_pod assertions
----------------------------------------------------------

                 Key: STDCXX-983
                 URL: https://issues.apache.org/jira/browse/STDCXX-983
             Project: C++ Standard Library
          Issue Type: Bug
          Components: TR1.4 - Metaprogramming and Type Traits
    Affects Versions: 4.3
         Environment: gcc-4.3
            Reporter: Travis Vitek
             Fix For: 4.3


I'm pretty confident that the following should compile and run without failure. It abbends
with SIGABRT with recent versions of gcc-4.3.

{{noformat}}
$ cat t.cpp && g++ t.cpp && ./a.out
#include <assert.h>

struct empty_t
{
};

struct trivial_t
{
  long value;
};

template <class T>
struct public_derived_t : T
{
};

int main ()
{
    assert (__is_pod(trivial_t));
    assert (__is_pod(public_derived_t<trivial_t>));

    assert (__is_pod(empty_t));
    assert (__is_pod(public_derived_t<empty_t>));

    return 0;
}
a.out: t.cpp:20: int main(): Assertion `__is_pod(public_derived_t<trivial_t>)' failed.
Aborted
