Answer Y here to compile extra debugging support code into malloc.
- Malloc debugging output may then be enabled at runtime using
- the MALLOC_DEBUG environment variable. Because this increases
- the size of malloc appreciably (due to strings etc), you
- should say N unless you need to debug a malloc problem.
+ Malloc debugging output may then be enabled at runtime using the
+ MALLOC_DEBUG environment variable.
+
+ The value of MALLOC_DEBUG should be an integer, which is interpreted as
+ a bitmask with the following bits:
+ 1 - do extra consistency checking
+ 2 - output messages for malloc/free calls and OS allocation calls
+ 4 - output messages for the `MMB' layer
+ 8 - output messages for internal malloc heap manipulation calls
+
+ Because this increases the size of malloc appreciably (due to strings
+ etc), you should say N unless you need to debug a malloc problem.
