Yes, I've had a failing VAM manifest itself with SegV crashes.
Eventually it died completely and wasn't recognized on boot;
once replaced, router was stable as-is.

Ken's right on, there are some classes of hardware faults,
namely feeding corrupted data into the system in-between 
validation points that could cause a software-triggered SegV
crash.

Hosing a pointer most commonly would be a software error, but
hardware can absolutely contribute.
