 I am attempting to calculate SHA1 hashes of very large ( > 1GB ) files.
 This works fine in MRI 1.9.2 but segfaults in macruby 0.8 and 1/27
 nightly.

 require 'digest/sha1'
 Digest::SHA1.file('some huge file').hexdigest

 The above code will segfault 100% of the time with files larger then 1GB.
 I can also produce the same segfault with the following:

 File.open('some huge file', 'rb') do |file|
      while blk = file.read(1024)
           #do stuff
      end
 end
