I tried it and it just points to stack like below:

==21171==  Uninitialised value was created by a stack allocation
==21171==    at 0x1BA18FE: tzload (tz.c:232)

Here is the code at line 232:

 229 static int
 230 tzload(const char * name, struct state *tz_state,
 231         const int doextend, tz_errno_t * errnop)
 232 {
 233         const char *            p = NULL;
 234         int                     i = 0;
 235         int                     stored = 0;
 236         ssize_t                 nread = 0;
 237         unzFile                 zfile = NULL;
 238         union {
 239                 struct tzhead   tzhead;
 240                 char            buf[2 * sizeof(struct tzhead) +
 241                                         2 * sizeof (struct state) +
 242                                         4 * TZ_MAX_TIMES];
 243         } u = {0};
