[Bug c++/33665] [4.1/4.2 regression] Bogus warning: `this.0' is used uninitialized in this function

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

------- Comment #1 from reichelt at gcc dot gnu dot org  2008-01-06 22:30 -------
Confirmed. Here's a further reduced testcase that triggers the warning
already with "-O -Wall":

================================
struct A {};

struct B : A
{
  double x, y;

  B() : x(), y() {}
};

inline B getB()
{
  return B();
}

struct C : B
{
  C() : B(getB()) {}
};

C c;
================================

bug.cc: In function 'void __static_initialization_and_destruction_0(int, int)':
bug.cc:7: warning: 'this.0' is used uninitialized in this function
bug.cc:7: note: 'this.0' was declared here

The bug appeared in GCC 4.1.2, but seems to be fixed on mainline.
