TestCase null_deref was failing in Win64:

The reason was symbols was not initilized. In fact, it was first inited
with a call to stack.Print(), which calls
WinSymbolizerTool::SymbolizePC, then InitializeDbgHelpIfNeeded().

Since the StackWalk was performed before the stack.Print(), stack frames
where not gathered correctly.

There should be a better place to initialize symbols. For now, this
patch makes the test happy.
