more gdb info in attchment

But recently, I met the deadlock problem again.
centOS 7.2 with glibc-2.17, which has already back ported the patch fff94fa(Avoid deadlock in malloc on backtrace (BZ #16159))
The main problem is the process does not abort, it hangs. M_CHECK_ACTION parameter is default value 3.
Backtrace from gdb is similar with BZ #16159, but different expection reason detected.
The 1st expection triggered by calling free func. The pointer to free is an address of array(calloc), and out-of-bounds access before.
So the 1st expection is "free(): invalid next size (normal)" and in malloc_printerr func malloc report the 2nd error
"malloc(): smallbin double linked list corrupted", then it hangs around in:
pthread_once
__GI___backtrace
More details please see attachment
