Compiling koffice cvs with gcc 3.4.0 20040201 will fail in 
filters/kword/pdf/FilterPage.cpp on line 316. 
 
(I will attach the FilterPage.ii file.)

Confirmed. Test case:

struct QChar {
    static const QChar null;
};
struct QCharRef {
    operator QChar() const;
};
struct QString {
    QCharRef operator[](int i);
};

QChar fillParagraph(QString s, int psi) {
    return psi ? QChar::null : s[psi];

By the looks of this, it looks like there are two different structs called QChar for some reason.

The standard is not clear.

Here, "QChar::null" is an lvalue of type "const QChar".  Meanwhile,
"s[psi]" is an rvalue of type "QCharRef".
                                                                                
According to [expr.cond], we try to convert each of the operands to
the type of the other.  The applicable language is:
                                                                                
  E1 can be converted to match E2 if E1 can be implicitly converted to
  the type that expression E2 would have if E2 were converted to an
  rvalue (or the type it has, if E2 is an rvalue).
                                                                                
where, here, "E1" is "s[psi]", and "E2" is "QChar::null".
                                                                                
The type that E2 would have if it were an rvalue is "const QChar"
because rvalues of class-type can be cv-qualified.  E1 can certainly
be implicitly converted to "const QChar" since:
                                                                                
  const QChar t = s[psi];
                                                                                
is valid; the cv-qualification of the left-hand and right-hand sides
is ignored in this context.
                                                                                
We then have:
                                                                                
   that conversion is applied to the chosen operand and the converted
   operand is used in place of the original operand for the remainder
   of this section.
                                                                                
Now, the questions:
                                                                                
- What is the type of this converted operand: "const QChar" or just
  "QChar" as returned by the conversion operator?
                                                                                
- What if the "QChar::null" had type "QChar" and the conversion
  operator returned "const QChar"?

I think the logic conclusion is that the type of both operands, after
the conversion, should be treated as the union of the cv-qualification
of the two converted operands.

I have asked Steve Adamczyk to open a core issue.

In the meantime, I'll look at implementing the suggested fix.
