User space memory management library

Hi,

I am in a big company which develop millions of code in an embedded
device. You know in embedded device the memory is very limited and we
want to see which application eats too much memory and at which time.

So is there a library(memory allocater wraper) can do following things:

1) It can record which module/file/line invoke the memory allocater.'
2) How large it allocates.
3) When it allocates.
4) When it frees it.

It seems that in development stage we can use it and in release version
we just define it to standard lib C malloc, free etc...

Just like this:

a (void)
{
libmm_malloc(); // records all the tings
libmm_free();
}

It is possilbe to develop one by ourself, but is there already exists?

Thanks a lot.

ABAI

    ... problem is that in doing so, an implementation of free is doing something not allowed by the standard, which gives it *no* leeway whatsoever to allow the memory to effectively vanish; it expressly requires the memory be available for subsequent allocation, therefore it *cannot* hand it back to the OS - doing so may make it unavailable for further allocation, by the conforming application which has every right to expect the memory is available - free's definition states this, absolutely and unequivocally. ...
