lifetime of a parameter or local variable ends
when you return from the function, any

passed to library
function.
Fatal
Run-time Error
Pointer expression you passed to the library
function is invalid because it refers to a
location in dynamic memory that you
deallocated with the function

memory is free, all pointers into that block of
memory are invalid.
