The compiler can't really help you (aside from maybe adding dereference 
checks everywhere) because you have a logic error, not something that can 
be statically determined. This is why debuggers exist. Whenever I get a 
segfault, I fire up GDB and recreate it. If you've compiled with -g, GDB 
can usually tell you the exact line the problem occurred on and a full 
backtrace to help you figure out how you got there.
