A small testcase

struct gomp_task {
  void *fn_data;
};
extern void *gomp_malloc (unsigned long int);
void GOMP_task (void (*fn) (void *), void *data,
        void (*cpyfn) (void *, void *),
        long arg_size, long arg_align)
{
  struct gomp_task *task;
  char *arg;
  task = gomp_malloc (sizeof (*task) + arg_size + arg_align - 1);
  __builtin_memcpy (arg, data, arg_size);
  task->fn_data = arg;
}

compiled with -m64 -mavx -O2.
