Chapter 7:

pg 148 Replace the first paragraph with

A value must be returned from a function that is not declared void
(however, main() is special; see sec3.2). Conversely, a value cannot
be returned from a void function. For example:
	int f1() { }			// error: no value returned
	void f2() { }			// ok

	int f3() { return 1; }	// ok
	void f4() { return 1; }	// error: return value in void function

	int f5() { return; }		// error: return value missing
	void f6() { return; }	// ok

pg 148 Add at the end: "A void function cannot return a value.However, a call of a void function doesn't yield a value, so a voidfunction can use a call of a void function as the expression in a return statement. For example:

	void g(int* p);

	void h(int* p) { /* ... */ return g(p); }	// ok: return of ``no value''
This form of return is important when writing template functions where the return type is a template parameter (see sec 18.4.4.2)." (recent standards change)

pg 450 replace the last paragraph of sec16.3.4 with "A constructor given two arguments of the same type can lead to an apparent ambiguity. For example:

	vector<int> v(10,50);	// vector(size,value) or vector(iterator1,iterator2) ?
However, an int isn't an iterator and the implementation must ensure that this actually invokes
	vector(vector<int>::size_type, const int&, const vector<int>::allocator_type&);
rather than
	vector(vector<int>::iterator, vector<int>::iterator, const vector<int>::allocator_type&);
The library achieves this by suitable overloading of the constructors and handles the equivalent ambiguities for assign() and insert() (sec16.3.6) similarly." (recent standards resolution)

Chapter 24:

pg 751-754 The examples using an enabling condition are wrong. I forgot to apply DeMorgan's law when I transcribed the examples from an

	if(A&&B) throw C();
form to
	Assert(!A || !B);
erroneously and confusingly writing
	Assert(A && B);
For example, String::check() on pg 752 should be
	inline void String::check()
	{
		Assert<Invariant>(!string_check || (p && 0<=sz && sz<TOO_LARGE && p[sz]==0));
	}
and g() on pg 753 should be
	void g(int* p, exception e)
	{	
		Assert(!g_check || p!=0, e);							// pointer is valid
		Assert(!g_check || (0<*p&&*p<=g_max),Bad_g_arg(p));	// value is plausible
		// ...
	}
In places, the commentary reflects the confusion.
