--- Comment #4 from pipcet at gmail dot com ---
I believe this invalid code triggers the same bug, and might be easier to
analyze:
extern int fn();
template
class X {
public:
template class Y {};
template void y() {}
X(F f)
{
Y y;
y.value();
}
};
int main() { const X x(fn); }
In both cases, an identifier is used twice ("y" here, "ptr" in the original
example), and renaming one instance to avoid the name clash avoids the ICE.
