I think I've also seen a few reports of programs exiting with
"Profiling timer expired" messages with 4.4. These can be caused
by stack overflows, since the p_timer[] array in struct pstats is
one of the things that I think lives below the per-process kernel
stack. I wonder if they are related? Stack overflows could result
in corruption of local variables, after which anything could happen.
That said, hardware problems are still a possiblilty.
