[Bug c++/13121] New: Inserting struct with valarray in map fails

[Uwe dot Seimet at seimet dot de]

Hello!

The sample code below demonstrates the bug. Struct A is not inserted correctly
into the map m. When running the sample problem the output is:

5
0

but it should be

5
5


Best regards,   Uwe

#include <map>
#include <valarray>
#include <iostream>

struct A 
{
  std::valarray <int> v;
  A (int i=0)
    : v (i)
  {}
};

int main (int, char**)
{
  std::map <void*, std::pair <A, bool> > m;

  A a (5);
  std::cout << (a.v.size ()) << std::endl;
  m [(void*)0] = std::make_pair (a, false);

  std::cout << (m [(void*)0].first.v.size ()) << std::endl;
  return 0;
}
