This is attribute related (removing attributes on the classes cause GCC not to crash).

Confirmed. I'll work on reducing the testcase.

------- Additional Comments From bangerth at dealii dot org  2003-11-24 17:33 -------
OK, here's a reduced testcase:
---------------------
struct __attribute__((dllimport)) Base {
  virtual inline ~Base() {}
};

struct __attribute__((dllimport)) Derived : public Base {
  bool operator== (const Derived& text);
  bool foo(const Derived &);
};


bool Derived::foo(const Derived &) {
  return 1;
}

bool Derived::operator== (const Derived& text) {
  return foo(text);
}
--------------------------------

g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc
x.cc:3: warning: `dllimport' attribute directive ignored
x.cc:8: warning: `dllimport' attribute directive ignored
x.cc: In member function `bool Derived::operator==(const Derived&)':
x.cc:16: internal compiler error: in build_base_path, at cp/class.c:278
Please submit a full bug report,

The ICE goes away if I remove the attributes. Interestingly, we
seem to replace the ICE by an infinite loop if we remove the
destructor of the base class...

------- Additional Comments From reichelt at gcc dot gnu dot org  2003-12-03 22:11 -------
Here's an even shorter testcase (without inheritance):

---------------------------------------------
struct __attribute__((dllimport)) A
{
    virtual ~A();
    void foo(const A&);
    void bar(const A&);
};

void A::foo(const A&)   {}
void A::bar(const A& a) { foo(a); }
---------------------------------------------

Btw, to get the infinite loop, you only have to make the destructor non-virtual.

For some reason with the attribute there, there are two copies of the type, one with and 
without the atrribute.

This code in build_base_path appears to trigger:

my_friendly_assert (code == MINUS_EXPR
                    ? same_type_p (BINFO_TYPE (binfo), probe)
                    : code == PLUS_EXPR
                    ? same_type_p (BINFO_TYPE (d_binfo), probe)
                    : false, 20010723);

code appears to be PLUS_EXPR, so it's the second part which is failing.
