I'm tracking memory usage in kpanel and I need a feature that 
--AFAIK-- is not
provided by tools such as ccmalloc and leaktracker.
I need a way to detect how much memory has been allocated between two 
execution
points. Suppose, for example, that I'm going through the execution 
with gdb and
I have the following example code:

   Foo* foo = new Foo(.....);

   fee = buildFeeTree(....);

I would like to call a function (eg.) get_allocated_memory() from gdb 
before
and after every step to know how many bytes have been allocated by the 
constructor
of Foo and during the execution of buildFeeTree().
I have tried to use the __malloc_hook, __realloc_hook and __free_hook 
of the 
glibc library, but somewhere in the runtime the __malloc_hook is reset 
to NULL.

Any help, please?

Thanks,

-- Pietro
