Summary of Memory Analysis errors

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.
