Summary: bug in pstore (ruby 1.8.2) on Windows ( Win XP) ?

Initial Comment:
The follow error occurs

c:/ruby/lib/ruby/1.8/pstore.rb:163:in `load': marshal data too short (ArgumentError)


when this code is run:

####################################
require "pstore"

id = 21
pstore = PStore.new("c:/testfile")
pstore.transaction do
	pstore["id"] = id
end

pstore.transaction do
	id = pstore["id"]
end
print id, "\n"
###################################

The code is run on WinXP
ruby version is 1.8.2

Solution:
I have to change pstore.rb line 101
from
        file = File.open(@filename, File::RDWR | File::CREAT)
to
        file = File.open(@filename, "a+b")
to solve this problem
