Sure. Here's a simple one:

File.open("myfile.txt") do |f|
  line = f.gets
  line =~ /./
end

You can run this script on two machines, with the same version of OS and 
ruby and the same myfile.txt but with different environment variable 
settings, and get it to crash on one but not the other. (One way: if the 
default external encoding on one machine is US-ASCII and myfile.txt 
contains any byte with the top bit set)

This is intentional behaviour in ruby 1.9.
