faulty source code

(On Debian/Sid/AMD64)

The attached file (with an incorrect __atomic_store) gives an ICE.

badatomicstore.c: In function ‘clear_s1’:
badatomicstore.c:9:6: internal compiler error: in tree_to_uhwi, at tree.h:3660
      __atomic_store(s->i_name, NULL, __ATOMIC_SEQ_CST);
      ^
Please submit a full bug report,


Of course, the instruction is incorrect; it should be

     __atomic_store_n(&s->i_name, NULL, __ATOMIC_SEQ_CST);
