Summary Machine::retrieveLastCaller should check for a NULL codeBlock

Reported 2008-09-29 17:28:06 PDT
Machine::retrieveLastCaller reads a CodeBlock out of the register file without checking for NULL. Since CodeBlocks in the register file can be NULL, it should check. I thought you could crash this code through something like "console.log.call(console, 'hello world')", but that doesn't quite do it. Still, we should just be safe and check for NULL.
