 If someone from Barclays Capital is writing programs that are being allowed to seg fault and they want to *ignore* the seg fault then I'm taking all my money away from Barclays Capital and keeping it away. Barclays Capital, the bank that likes to say "seg fault".

 Your code can't possibly seg fault - our governments are always telling us banks are too big to fail.

 That's enough banker bashing.
