Exception 7 from .kernel_fault_action

[erlo]

Can this kind of exception be caused by a user program?
----- program interrupt exception ----
Exception 7 pid: 0 pptr 0(0) tptr a08cf160(1) flags 200018 (<kernel> 00000000)

From running nm it seems like .kernel_fault_action is the trigger - but what can trig this?
