The following code snippet gets an error when compiled with gcc-3.4-20030102

gcc-3.4-20021224 (pre-new parser) works...

typeid.cxx:
-------------------
#include <typeinfo>

struct A {
    virtual ~A() {}
};

void
foo(A* a)
{
    typeid(*a).name();
}

void
bar(A* a)
{
    const std::type_info& t = typeid(*a);
    t.name();
}
-------------------

% g++34 typeid.cxx
typeid.cxx: In function `void foo(A*)':
typeid.cxx:10: error: request for member `std::type_info::name() const' in `
   __cxa_bad_typeid()()', which is of non-class type `const std::type_info&'

Note how 'bar(A*)' compiles fine.

Is this a parser bug, or is this the standard mandated behaviour? (I'd guess a bug...)

State-Changed-Why:
    I'm closing it as a duplicate of c++/9128, at the same time
    marking the latter as a 3.4 regression to be sure.
