I ran all the commands you suggested with no problems.

The problem function is this in the Rails code:
def generate_secret_with_urandom
  return File.read("/dev/urandom", 64).unpack("H*")[0]
end

If I put that function directly in its own Ruby code file and run it
from Cygwin, there is no problem, so I guess it has something to do
with how it's called.

Also, for some reason you can change the function to this in the Rails
code and everything works.

def generate_secret_with_urandom
  puts "meaningless output"
  return File.read("/dev/urandom", 64).unpack("H*")[0]
end

I'm going to re-strace things with the modified function and see what
the difference might be.
