#### 8.4.3 Debugging the heap

Free Pascal provides a unit that allows you to trace allocation and deallocation of heap memory: heaptrc.

If you specify the -gh switch on the command line, or if you include heaptrc as the first unit in your uses clause, the memory manager will trace what is allocated and deallocated, and on exit of your program, a summary will be sent to standard output.

More information on using the heaptrc mechanism can be found in the User’s Guide and Unit Reference.
