Yes it is the same.
Reduced testcase:
typedef __builtin_va_list __gnuc_va_list;
namespace std { 
  class type_info   {};
}
template
void f(t)
{
  typeid(t);
}
typedef __gnuc_va_list va_list;
void calla(::va_list l) {
  f(l);
}

I almost positive it is the same issue as PR 72809 (though using typeinfo
instead of throw).

I not sure this is valid, but GCC still shouldn't crash.
