Very many thanks to Wolfgang Bangerth for volunteering to reduce the
8,000 lines of my original preprocessed source to the following:

struct S {
  void foo() {
     for (_ptr; ;) {}
     _ptr = 0;
    }
};

If the C++ front-end reviewer of my patch could recommend a name for
this testcase, I'll happily add it to testsuite/g++.dg when I commit
my fix for this ICE.
