This is symptomatic of gettimeofday() returning a out of range
tv_usec value. There should be a wrapper around the calls to
gettimeofday() to correct tv_usec however when I run nm on the
objects in the build tree they are calling gettimeofday directly.
From src/freebsd/include/port_after.h as distributed by ISC.
int isc__gettimeofday(struct timeval *tp, struct timezone *tzp);
#define gettimeofday isc__gettimeofday
