Asterisk without calls, only has 40 extensions,  after 12  or 24 hours working (without traffic ) starts to throw this message, at the moment without crash.  

The problem appears if  asterisk is started by systed or if you start with asterisk,  also as root and as asterisk user.

It seems that each line of these :
[Nov 24 22:19:48] ERROR[20561]: astobj2.c:136 INTERNAL_OBJ: FRACK!, Failed assertion bad magic number 0x1fca for object 0x7f28a02be6e8 (0)

Could correspond for each extension because this line appear as 40 times and then  as 40 times:
