Following program crashes beam VM. Is it possible to check
available resources or magic version headers or received packet lenght
before trying to allocate silly amount of memory?

best regards,
taavi

-module(test).

-export([test/0]).

test() ->
Port = erlang:open_port({spawn,"echo blaah blaah blaah blaah"},
[binary,{packet,4},exit_status]),
loop().

loop() ->
receive
{'EXIT', Var, PosixCode} ->
exit(PosixCode);
Message ->
io:format("Messgae=~p~n",[Message])
end,
loop().
