Internal compiler error

[Christopher Grinton]

First of all, let me say thanks for the great work everyone is doing
on the egcs project; it is exciting to see some of the latest
developments that have been going on with gcc.

The following code causes an internal compiler error with egcs-970910
(seg fault at the call to comptypes at call.c:5642 because the
arguments TREE_OPERAND (ics[12], 0) to the TREE_TYPE macros are both
0).

It compiles without error using g++ 2.7.2.1 which is not correct
either, since the == in f is ambiguous (candidates are
operator==(int,int) and operator==(const MyInt&, const MyInt&)).

I am running Debian linux 2.0.30. If you would like any more
information about my system, please let me know.

class MyInt
{
public:
	MyInt(int = 0) {}
	operator int() const {return 2;}
};

bool operator==(const MyInt& a, const int& b)
{
	return (int)a == b;
}

bool operator==(const MyInt& a, const MyInt& b)
{
	return (int)a == (int)b;
}

bool f()
{
	return 3 == MyInt();
}

Regards,
Chris
