---------------------------------------------------

OS X debug (--enable-debug) build: 

Getting the following segfault about 5 seconds after startup with latest trunk:

#0  0x00007fff88b4cfe6 in __kill ()

$12 = {
  ethr_stat_offset = 2920, 
  global = 0x100d563b0, 
  num_stats = 0, 
  max_stats = 16, 
  mutex = {
    __sig = 0, 
    __opaque = '\0' <repeats 55 times>
  }
}
(gdb) fr 2
#2  0x0000000100280639 in ink_mutex_acquire (m=0x101801448) at ink_mutex.h:96
96	    abort();
(gdb) l
91	
92	static inline int
93	ink_mutex_acquire(ink_mutex * m)
94	{
95	  if (pthread_mutex_lock(m) != 0) {
96	    abort();
97	  }
98	  return 0;
99	}


Looks like the mutex for rsb is NULL.
