Segmentation fault (core dumped) problems

[jamesss]

I've installed Arch Linux on my Raspberry Pi model B. I'm currently running the 3.10.33-1-ARCH kernel and the system is up to date. I've been running into problems with seg faults though, which at first prevented ssh access. After re-installing from a backup image, I now have an issue running the aws command (see strace below).

As far as I understand it, seg faults are usually caused by problems with shared memory, but could this be caused by a dying SD card?

Any advice appreciated.
