Dynamic Memory Defects

Defects for dynamic memory coding errors, freed pointers, memory leaks, unprotected memory

These defects are errors relating to memory usage when the memory is dynamically allocated. The defects include:

Freeing dynamically allocated memory
Unprotected memory allocations

Polyspace Results

`Alignment changed after memory reallocation`	Memory reallocation changes the originally stricter alignment of an object
`Deallocation of previously deallocated pointer`	Memory freed more than once without allocation
`Invalid free of pointer`	Pointer deallocation without a corresponding dynamic allocation
`Invalid deletion of pointer`	Pointer deallocation using `delete` without corresponding allocation using `new`
`Memory leak`	Memory allocated dynamically not freed
`Mismatched alloc/dealloc functions on Windows`	Improper deallocation function causes memory corruption issues
`Unprotected dynamic memory allocation`	Pointer returned from dynamic allocation not checked for `NULL` or `nullptr` value
`Use of previously freed pointer`	Memory accessed after deallocation
