[Bug c++/37473] New: typedef results in wrong function call linkage

["amodra at bigpond dot net dot au" <gcc-bugzilla at gcc dot gnu dot org>]

The following testcase compiled with -O -fPIC results in a non-PLT call to
A::check.  On x86_64 that means an R_X86_64_PC32 reloc, which the linker later
correctly complains about if we are building a shared library.  Curiously, if
either or both of the typedefs are removed, you get the code I'd expect.

typedef struct
{
  int check ();
} A;

typedef struct
{
  A a;
  int validate ();
private:
  int check ();
} B;

int
B::check ()
{
  return a.check ();
}

int
B::validate ()
{
  return check ();
}

int
doit ()
{
  B b;
  return b.validate ();
}
