[Bug c++/13458] New: Segfault on recursive member template; maybe duplicate of 13289.

["sander at 01-creations dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The bug did not occur if either the data member z of outer<i1> :: inner was
removed or if the local variable a was removed.

Maybe a duplicate of bug #13289.

The code is invalid as far as I know.

.ii file:
----------------
# 1 "templtest1.cpp"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "templtest1.cpp"
template<int i1> struct outer {
 template<int i2> struct inner;
};

template<int i1, int i2> struct outer<i1> :: inner {
 outer<i1>::inner<i2-1> z;
};

int main(void) {
 outer<5>::inner<10> a;
}
