I am running the Cog image on the stock Squeak 4.1 vm. I was testing the Cryptography package. There are two test cases that are now failing: CryptoRigndaelCBCTest>>#testByteArrayFromHexString and CryptoX509Test>>#testSignatureValidation for unknown reasons.
I decided to Run Coverage. I am not really sure what this does, but I was trying to find a way to get performance numbers and then compare to the Cog VM.
I got the attached crash dump.
