[Ironruby-core] byte[] to ruby string

I don't even get that far. When I do a File.read or a System::IO::File.read_all_bytes from IronRuby (iirb.exe), I get this (works OK in MRI):

irb(main):001:0> File.read("c:\\temp\\clickhere.png")
IOError: Not enough storage is available to process this command.

        from mscorlib:0:in `WinIOError'

I'm struggling with converting a byte array into a ruby binary string.
Does anybody know how to make something like this pass?

require 'test/unit'
include System::IO
class Binstring < Test::Unit::TestCase

   def test_binstring_bytea
     fileName = 'flowers.jpg'

     #Ruby way
     data1 = File.read(fileName)

     fs = FileStream.new(fileName, FileMode.Open, FileAccess.Read);
     br = BinaryReader.new(fs);
     numBytes = FileInfo.new(fileName).Length;
     buff = br.ReadBytes(numBytes);
     data2 = System::Text::ASCIIEncoding.new.GetString(buff).to_s

     assert data1 == data2
