[Bug c++/34750] [4.1/4.2 Regression] ICE in fold_convert, at fold-const.c:1955

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

------- Comment #5 from reichelt at gcc dot gnu dot org  2008-01-12 19:23 -------
Even further reduced testcase:

=================================
struct A
{
  template<typename T> A(T);
};

class C;

struct B : A
{
  B(const C& c) : A(c) {}
};

struct C
{
  C(const C&);
  C();
  C& operator= (const C&);
};

B b = C();
=================================

bug.cc: In constructor 'B::B(const C&)':
bug.cc:10: internal compiler error: in cp_expr_size, at
cp/cp-objcp-common.c:100
Please submit a full bug report, [etc.]

This is really invalid code (C is used before it is defined).

The bug was fixed on mainline between 2007-10-13 and 2007-11-13.
