[Bug c++/22545] New: ICE with pointer to class member & user defined conversion operator

[paul dot woegerer at nsc dot com]

Compiling the example below with g++ from snapshot 4.1.0 20050716 causes
the following error message:

> g++ -S cpp_parse_internal_error.cpp

cpp_parse_internal_error.cpp: In function 'int main()':
cpp_parse_internal_error.cpp:23: internal compiler error: tree check: expected
class 'type', have 'exceptional' (error_mark) in is_complete, at cp/call.c:1567

Compiling the same example with 3.4.4 works perfectly and correctly returns 13
as result. The behaviour does not depend on the optimization level (O0, O3 all
the same)

------------------------------------------- cpp_parse_internal_error.cpp

struct A {
  int member;
  A() : member(13) {}
};

A a;

struct B {
  operator A*() { return &a; }
};

B b;

int A::* member_pntr = &A::member;

int main()
{
  // That one WORKS
  // A *a_pntr = b;
  // return a_pntr ->* member_pntr;

  // But this one causes an INTERNAL ERROR
  return b ->* member_pntr;
}
