Hi Experts, I am running a script which initiates and access data at multiple places. The issue is that this script is creating core dumps and these core dump number match exactly the same number of times I see the below error. Ex :- Till now there are 6 core files which has been created and I see the below errors 6 times.

Code:
98349.198649] traps: Sigma[86409] general protection ip:2b0d9a8bd56b sp:2b1345afce70 error:0 in libc-2.17.so[2b0d9a841000+1b6000]

I tried researching it but most of the times it says some issues with the memory. I ran memtest+ overnite and it passed without any issues. I ran mprime torture test and all passed.

My kernel version is 4.4.6
[code]uname -a
4.4.6-gentoo #2 SMP Mon Sep 5 21:20:22 IST 2016 x86_64 Intel(R) Xeon(R) CPU E5-2697 v3 @ 2.60GHz GenuineIntel GNU/Linux

Please help me as to how this can be resolved. Thanks for all your help in advance.

It's a software bug, because it crash at same ip (relative to libc).

Yes. Fix the program not to pass invalid input to libc.
