  j.d = 0;
  __builtin_unreachable ();


Considering void g::i(a)/4 with 31 size
 to be inlined into void test()/5 in t6777.cc:40
 Estimated badness is -1.161290, frequency 1.00.
Introduced new external node (void __builtin_unreachable()/23).
New minimal size reached: 40
node context cache: 1 hits, 0 misses, 1 initializations
