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};
Thanks,
