Extended Description

If you run this you can see that the invocations of operator ++ gets while operator << has a valid location

// Command line: c-index-test -test-load-source all file.cpp

struct A
{
int value;
A & operator ++ () // preincrement
{
value += 1;
return (*this);
}
A & operator ++ (int) // postincrement
{
value += 2;
return (*this);
}
A & operator << (int rhs)
{
value = 23;
return (*this);
}
};

A a;

void func (void)
{
++a; // CHECK: :0:0: DeclRefExpr=operator++:6:7
a++; // CHECK: :0:0: DeclRefExpr=operator++:11:7
a << 23; // CHECK: file.cpp:29:5: DeclRefExpr=operator<<:16:7
}

The underlying issue is that the ast nodes don't have locations:

void func() (CompoundStmt 0x7f918403dde0 <t.cpp:24:1, line:28:1>
(CXXOperatorCallExpr 0x7f918403d100 <line:25:3, col:5> 'struct A' lvalue
