Think this through, Christian.
You're declaring a variable inside a function.
Now, you're pointing to that variable.
You've now left the function -- all automatic (think: local) variables are 
deinitalized. Poof -- they no longer exist.
BUT THE POINTER STILL POINTS TO IT.
Bad thing. Very bad thing. You're pointing to a location in memory that does 
not neccesarily contain -- well, anything. I don't even want to THINK about 
what'd happen if you tried to write to it.
