Erlang/Windows stabilty - a newbie question.

Hi,
This is my first post to the the list - I've been coding for about
twenty-five years... but currently I'm an Erlang newbie :)
At the moment, I'm having a bit of a problem with program stability
using Erlang and I wondered if anyone here could help. I'm using
R10B-10 on WinXP (2GHz/1GbRAM) and I've narrowed the issue to the
following code which I've wrapped in a simple module to demonstrate:
-module(testtokens).
-export([start/0]).
start() ->
erlang:display(time()),
FILENAME = "test.txt",
case file:read_file(FILENAME) of
{ok, Data} ->
TESTSTRING = binary_to_list(Data);
{error, Reason} ->
TESTSTRING = ""
end,
string:tokens(TESTSTRING, " "),
time().
The code is intended to load a file, convert it to a string and then
split the loaded string. To test Erlang under pressure - I made
'test.txt' - 14Mb large. When I run it repeatedly... this is what
happens...
Erlang (BEAM) emulator version 5.4.13 [threads:0]
Eshell V5.4.13 (abort with ^G)
1> c(testtokens).
./testtokens.erl:11: Warning: variable 'Reason' is unused
{ok,testtokens}
2> testtokens:start().
{19,13,40}
{19,13,50}
3> testtokens:start().
{19,13,55}
{19,14,3}
4> testtokens:start().
{19,14,7}
{19,14,19}
5> testtokens:start().
{19,14,22}
{19,14,50}
6> testtokens:start().
{19,14,53}
Abnormal termination
Every time it crashes. Thus my question is... am I doing something
intrinsically dumb/non-erlang here.... or is it a bug? I know Erlang
doesn't pretend to be an efficient sequential processor... but I didn't
expect this.
If you've got any advice I'd really appreciate it.
Thanks,
Kyle.
