[Bug c++/38485] New: possible regression: expected primary-expression at end of input

["gcc at spatium dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Compressed .ii file goes as attachment.

gcc 4.3.2: (reports no errors)

my gcc:

g++ -c kded_kephal_automoc.ii

The problem is at line 9355 of the .ii: (comment it out and it works)

void translateToOther(QMap<int, QRect> & layout, Output * base, QMap
<int, int> match = (QMap<int, int>()));

...and from what I could figure out, it is the right-side of the '=' default
parameter assignment.

>From my understanding, the code sould be equivalent to this small test case:

template <typename T1, typename T2> class blah {
        T1 whatever1;
        T2 whatever2;
        public:
        inline blah() {}
        inline T1 get1() { return whatever1; }
};

int foo(blah <int, int> bar = (blah <int, int> ())) {
        return bar.get1();
}

int main(void) {
        return foo();
}

However, this code compiles and runs perfectly on my gcc.
