[Bug c++/25814] New: Request for new warning

[Raimund dot Merkert at baesystems dot com]

I'd like to request a warning to notify that a statement like "X x(const Y&)"
is parsed as function declaration and not a definition of variable x. See the
code below.

At least as couple of PRs have been filed (9217,19503) on this topic.
I've just spent at least 2 hrs trying to figure out why my constructor and
destructor were not called and did not show up in the assembly code either. 

I think this particular problem might affect users that use the
resource-acquisition idiom. The real problem is that the code compiles and
links and runs without problems, except it doesn't actually work.


#include <cstdio>

struct Y {};

struct X {
  inline X (const Y&)
  {}

  inline ~X ()
  {
    ::std::printf("1\n");
  }

};

int main()
{
  X x(Y());
  return 0;
}
