Missing Allocation

Occurs when an invalid pointer is passed to a deallocation function. The invalid address may point to a previously released heap block.


Code Location



Deallocation site

If present, represents the location and associated call stack from which the memory block referenced by the address was previously deallocated.

The previous deallocation makes all subsequent deallocation attempts invalid.


Invalid deallocation site

Represents the location and associated call stack attempting the deallocation.

C Example

char* pStr = (char*) malloc(20);
Fortran Example

integer, target :: b(100)
integer, pointer :: pmiddle
pmiddle => b(4)
DEALLOCATE( pmiddle )
Possible Correction Strategies
