Description of problem:

I just tried to compile package festival-1.4.2-19, from Redhat
Fedora Core 1.

The compiler said

1.

EST_Pathname_unix.cc(148): warning #879: returning reference to local
variable

The source code is

EST_Pathname &operator += (EST_Pathname p, const EST_Pathname addition)
{ p = EST_Pathname::append(p, addition); return p; }

I think the compiler is correct. Maybe it would be better to have the
first parameter as a reference ?

EST_Pathname &operator += (EST_Pathname & p, const EST_Pathname addition)
{ 
	p = EST_Pathname::append(p, addition); 
	return p; 
}


2.

EST_Pathname_unix.cc(150): warning #879: returning reference to local
variable

Duplicate.
