Summary of error messages for Memory Analysis

The following table shows a summary of potential error messages you might encounter during memory analysis:

Message	Caused by	Description
`no errors`	No errors	No errors
`allocator inconsistency - Malloc chain is corrupted, pointers out of order`	A buffer overflow occurred in the heap.	The heap memory is corrupted.
`allocator inconsistency - Malloc chain is corrupted, end before end pointer`	A buffer overflow occurred in the heap.	The heap memory is corrupted.
`pointer does not point to heap area`	The illegal deallocation of memory.	You attempted to free non-heap memory.
`possible overwrite - Malloc block header corrupted`	A buffer overflow occurred in the heap.	The heap memory is corrupted.
`allocator inconsistency - Pointers between this segment and adjoining segments are invalid`	A buffer overflow occurred in the heap.	The heap memory is corrupted.
`data has been written outside allocated memory block`	A buffer overflow occurred in the heap.	The program attempted to write data to a region beyond allocated memory.
`data in free'd memory block has been modified`	Attempting to use memory that was previously freed.	The program is attempting to write to a memory region that was previously freed.
`data area is not in use (can't be freed or realloced)`	A buffer overflow occurred in the heap.	The heap memory is corrupted.
`unable to get additional memory from the system`	All memory resources are exhausted.	There are no more memory resources to allocate.
`pointer points to the heap but not to a user writable area`	A buffer overflow occurred in the heap.	The heap memory is corrupted.
`allocator inconsistency - Malloc segment in free list is in-use`	A buffer overflow occurred in the heap.	The heap memory is corrupted.
`malloc region doesn't have a valid CRC in header`	A buffer overflow occurred in the heap.	The heap memory is corrupted.
`free'd pointer isn't at start of allocated memory block`	An illegal deallocation of memory.	An attempt was made to deallocate the pointer that shifted from its original value when it was returned by the allocator.
