This fails to compile; those variables require initialization:


../../testcases/t_time32.c: In function 'main':
../../testcases/t_time32.c:12:5: error: 't' may be used uninitialized 
[-Werror=maybe-uninitialized]
   12 |     _ctime32(&t);
      |     ^~~~~~~~~~~~
In file included from ../../testcases/t_time32.c:3:
