------- Comment #3 from reichelt at gcc dot gnu dot org  2008-02-15 08:19 -------
Confirmed. This is a serious problem IMHO. Here's a valid example that crashes
for me:

============================
#include<vector>
#include<string>

struct A
{
  std::string s;
};

struct B
{
  B();
  std::vector<A> v;
};

B::B() : v(0) {}
============================

Reduced testcase:

============================
struct A
{
  A();
  A(const A&);
};

struct B
{
  A a;
};

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

C c;

------- Comment #5 from reichelt at gcc dot gnu dot org  2008-02-15 09:05 -------
The (valid!) testcase in comment #4 gives the following error message:

bug.cc:17: error: void value not ignored as it ought to be
bug.cc:17: internal compiler error: tree check: expected class 'expression',
have 'exceptional' (error_mark) in bot_manip, at cp/tree.c:1480
Please submit a full bug report, [etc.]
