Use the debugger .. you are a programmer!!!!!!!

When it breaks it will give you the pointer that is involved ... now look at all code that uses the pointer.

Also actually bother to look at any warning the compiler is spitting out.

The other thing you can have done is forgot to initialize the pointer and you are assuming it is zero.
pointer p;      // not initialized
pointer p = 0;  // initialized

This can give the weird behaviour that in debug mode the code will work but in release mode it will crash. The reason is in debug mode the compiled code takes the time to zero all variables for you and so both codes act the same, in release mode it will not zero variables and "p" will be initialized at some garbage value.

You can generally pick this problem off by turning your warning level up to 4 on the compiler ... it will spit a warning ... "Possible use of uninitialized pointer"
In vino veritas
