This tools is promising and seems to work. But I'd have some questions about the log entries.
- what does ELogContentOnFree means?

This means that the content of the cell will be logged when the cell is freed.

- Could you please detail the R: (realloc?) line in the log file? An example that confuses me below. What is that 0 in the realloc?

Yes, R: is a reallocation. Here is the code.

<source>

TAny* RNBHeap::ReAlloc(TAny* aPtr, TInt aSize, TInt aMode)

{

TInt oldLen=0;

if(aPtr)

oldLen=AllocLen(aPtr);

TAny* cell=RHeap::ReAlloc(aPtr, aSize, aMode);

if(iMode & ELogRealloc)

{

TBuf<200> logStr;

_LIT(KFmt, "\nR: 0x%08x %d 0x%08x %09d %09d");

logStr.Format(KFmt, cell, oldLen, aPtr, aSize, aMode);

iLogger.Log(logStr);

}

return cell;

} </source>

- What is that 4bytes different on allocated and reallocated buffers. See example above where 0x559036b8 is allocated for 32bytes, and later it's 36 and

This is just the difference between size of the allocated data and the size of the cell, which contains the points to the next cell on the heap.

Thanks!

I am glad it was interesting to someone. It could probably be developed a bit more. It was just something I bashed out over a couple of days out of interest.
