Summary:                    Segmentation fault after almost exactly ~ 500
finished SIP over TCP calls.
Description: 
I reproducibility get a Segmentation fault after almost exactly ~ 500 SIP
over TCP calls.

To ensure this is TCP related i have done the same test with SIP over UDP
-> no crash.


The gdb output:

astmm.c line 132 (__ast_alloc_region): '&reglock' really deep reentrancy!

Program received signal SIGSEGV, Segmentation fault.

just tested the same with 1.6.0 -> with 1.6.0 no crash. even after 10000
calls with this stress tool setting:
