--- Comment #1 from Volker Reichelt <reichelt at gcc dot gnu.org> ---
Confirmed.
Here's a simplified testcase that produces less error message before crashing:
===============================
template<int> struct A
{
typedef int ::X;
};
A<0> a;
===============================
The problem might be related to PR60200.
