After analyzing a build failure of wfmath with gcc-4.2, I condensed the issue
it was having to the following test case:
template <class T, class U = int> class A { public: T x1; U x2; };
template <template<class> class container_with_x1>
int f(const container_with_x1<int>& y) {
return y.x1;
}
int g() {
A<int> y;
return f(y);
}
This code compiles with g++-4.1, but fails with g++-4.2 and the snapshot of
g++-4.3 currently in Debian's gcc-snapshot package. My question is: is this
valid code or not?
