[Bug c++/26691] New: Wrong code for constructor with default value

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The compiler creates wrong code for the following valid OpenMP-C++
code snippet when compiled with "-fopenmp":

=======================================
#include<cstdio>

struct A
{
   int n;
   A(int i=3) : n(i) {}
};

int main()
{
    A a;
#pragma omp parallel private (a)
    std::printf("%d\n", a.n);

    return 0;
}
=======================================

Instead of OMP_NUM_THREADS times the output "3"
I get one "1" and OMP_NUM_THREADS-1 times "0".

In addition I get a bogus warning with "-O -Wall -fopenmp"
which is probably just another symptom of the problem above:

bug.cc: In function 'void _Z3foov.omp_fn.0(void*)':
bug.cc:6: warning: 'i' is used uninitialized in this function
