I don't have an ARM architecture machine, but the faulting
address looks like it may have been loaded from a corrupted
pointer value (0000ffff8027e048 instead of ffff8027e048----)
The code in question uses some list primitives, were there any
warning messages about list corruption prior to the crash?
There is no warning message abort list corruption or other corruption
prior to the crash.
