* Debugging versions of various heap related functions are combined
|

|
|
* here. The debugging versions include assertions and also print
|
||
|
|
* (to standard error) the function called along with the amount
|
||
|
|
* of memory allocated, and where the memory is pointing. The
|
||
|
|
* format of the log message is standardized.
