Redis 3.2.11 crash by signal: 11

[jm252409]

Hello, the following issue occurs when running any programs using redis on our ARM 9 processor, custom linux distribution. Is there any help you can provide based on the information below?

Any information you need that I can provide I will gladly provide.

Below is an example of the bug occurring while running the redis-benchmark utility.

Edit1: Note: we ran the redis server memory test tool (as suggested at the bottom of the bug report) and it passed.

Thanks
