>Description:
The code below causes the following output.

bash-2.05a$ /usr/local/bin/g++ -Wall ./ExceptionSpecCtor.cpp
ExceptionSpecCtor.cpp:13: error: parse error before `)' token
ExceptionSpecCtor.cpp:14: error: declaration of `Derived::Derived()' throws
   different exceptions
ExceptionSpecCtor.cpp:9: error: than previous declaration `Derived::Derived()
   throw (Base::E)'

Note that if I comment c-tor out everyhting compiles fine even though foo () member functions uses semantically the same construct.

--------------------------------------
struct Base
{
  class E {};
};

struct Derived : public virtual Base
{
  Derived () throw (E);
  void foo () throw (E);
};

Derived::Derived () throw (E)
{
}

void Derived::foo () throw (E)
{
}
