Mismatched Allocation/Deallocation
Occurs when a deallocation is attempted with a function that is not the logical reflection of the allocator used.
ID | Code Location | Description |
|---|---|---|
1 | Allocation site | Represents the location and associated call stack from which the memory block was allocated. |
2 | Deallocation site | Represents the location and associated call stack attempting the deallocation. |
Example
char *s = (char*)malloc(5); delete s;
Possible Correction Strategies
Use the appropriate deallocation function to return the memory block to the heap after its last use.
