Might be a dup of PR63584.

PR63584 does not produce ICE in 5.0

--- Comment #4 from Kai Tietz <ktietz at gcc dot gnu.org> ---
This sample is undefined behavior. It will use delete on the allocated memory,
and not delete [] as it would need.
Additionally the type 'int [n]' is no valid type for template argument.

Reduced:
template<typename T> struct shared_ptr { };
template<typename T, typename Arg>
shared_ptr<T> make_shared(Arg) { return {}; }
auto f(int n){
return make_shared<int[n]>(1);
}

--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Further reduced so it doesn't rely on any C++11 or C++14 features:
template<typename T> struct shared_ptr { };
template<typename T, typename Arg>
shared_ptr<T> make_shared(Arg) { return shared_ptr<T>(); }
void f(int n){
make_shared<int[n]>(1);
}
