I've been working away trying to figure it out, and I can't. Are we sure this is an invalid pointer? I'm going to try running a shared memory test from RTAI's showroom and see if it works there.
If it doesn't work, then maybe I can figure this out as it'll be an RTAI problem. If it does work, then the issue points to LinuxCNC. Not definitively, but more likely.
