            Bug ID: 57480
           Summary: struct with a va_list considered as non-POD
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED

C++ frontend marks structs with va_list as non-POD.
This problem is probably related to 31488.

roman@work:~$ cat va_list_is_not_pod.cc 
#include <stdarg.h>
#include <type_traits>

struct fiber {
    va_list va;
};

int
main(int argc, char *argv[])
{
    static_assert(std::is_pod<struct fiber>::value, "Should be POD");
}


roman@work:~$ g++ -std=c++11 va_list_is_not_pod.cc -o test
va_list_is_not_pod.cc: In function âint main(int, char**)â:
va_list_is_not_pod.cc:11:5: error: static assertion failed: Should be POD
