I recently updated glibc from release 2.31 to release 2.32 on Gentoo Linux running on a 32-bit armv7 machine. Ever since that the ntpd from openntpd doesn't startup any more.

Digging deeper I found that the forked 'ntp_main' instance of ntpd dies with a SIGSEGV when executing the the adjtime() glibc function call in the following function:


```
double                                                                            
getoffset(void)                                                                   
{                                                                                 
        struct timeval  tv;                                                       
>>>>    if (adjtime(NULL, &tv) == -1)                                             
                return (0.0);                                                     
        return (tv.tv_sec + 1.0e-6 * tv.tv_usec);                                 
}
```

The issue seems to stem from glibc git commit 0308077e3a4ff1c123cdddd311f55a2ecdd3115c where the newly introduced __adjtime 32-bit wrapper cannot handle a NULL pointer itv input parameter.

```
+#if __TIMESIZE != 64
+libc_hidden_def (__adjtime64)
+
+int
+__adjtime (const struct timeval *itv, struct timeval *otv)
+{
+  struct __timeval64 itv64, otv64;
+  int retval;
+
+  itv64 = valid_timeval_to_timeval64 (*itv);
+  retval = __adjtime64 (&itv64, otv != NULL ? &otv64 : NULL);
+  if (otv != NULL)
+    *otv = valid_timeval64_to_timeval (otv64);
+
+  return retval;
+}
+#endif
```
