The source below gives a segfault on GCC 4.0.1.  Spun off from Bugzilla Bug 22604, per Andrew Pinski, 
since he said it was a separate issue with the same symptom.  PalmSource bug 105158.

Source:
class nameOne : public nameTwo, public nameThree, public nameFour, public nameFive, public 
nameSix
{
 void nameSeven(const nameEight &name, const nameNine & icon);
 virtual void nameSeven(const nameEight& name, const nameTen &icon);

Confirmed,  the main reason why I said it was a different bug is because the backtraces are different.  
The second reason why I know it is a different bug is that this bug we crash in 3.4.0 also (though with
"t.cc:2: confused by earlier errors, bailing out" but that is just an ICE after a couple of errors).

Less invalid ;-) testcase:

==========================
struct A
{
    void foo();
    virtual void foo();
};
==========================

This crashes since gcc 3.0.
