The 'null pointer assignment' is execution error which occured
during program execution and is detected on end. To find where
it occurs, should use debugger which can display actual value
of *(0L) (or *NULL) and check when it changes. Or: try put exit(0)
anywhere in code, if error still occurs put it in place executed
earlier, if not remove and put in place executed later, until
a instruction is located. The message means an assignment was
done to address pointed by NULL, e.g. a=NULL; *a=something.
(it occurs usually if someone forgets to initialize pointer)
