I also found this:
(on unix/mac, on windows use some other program)
> Port = open_port({spawn, "cat"}, []).
> erlang:port_set_data(Port, {1,2,3}).
true
> erlang:port_get_data(Port).
... hmm my cpu skyrockets and the computer dies a bit :-)
then
beam.smp(41283,0xb06bb000) malloc: *** mach_vm_map(size=1799625657810944) failed (error code=3)
*** error: can't allocate region

Crash dump was written to: erl_crash.dump

"Installing applications can lead to corruption over time. Applications gradually write over each other's libraries, partial upgrades occur, user and system errors happen, and minute changes may be unnoticeable and difficult to fix"
