> 28219 has a testcase

It does not have a full testcase as you also need the other PCH header file to
try it out.

I'm currently configuring with --disable-libstdcxx-pch to work around
the problem.

[reichelt at gcc dot gnu dot org]

------- Comment #12 from reichelt at gcc dot gnu dot org  2006-07-12 15:03 -------
Reduced (from PR 28219) testcase:

=============================
template<int> struct A
{
  enum { a, b = a };
  void foo(A<b>);
};
=============================

bug.h:4: internal compiler error: tree check: expected integer_cst, have
const_decl in tree_int_cst_sgn, at tree.c:4517
Please submit a full bug report, [etc.]

If I replace "A<b>" by "A<a>" I get a segfault instead.
The testcase crashes since GCC 4.0.0.
The code compiles fine if I compile it as regular C++ file and not
as C++-header.
