Removing memory leaks on Symbian OS

Removing memory leaks on Symbian OS is really a hairy thing. Just in case you have to do programming on Symbian OS, if you get a panic with the reason code "ALLOC 0x<32bit-hex>", use either the technique described on this page. If you don't have MS Visual Studio (like me, I'm stuck with Metroworks CodeWarrior), use the following code snippet:

TBuf<255> buf;

buf.Format(_L("CFileDescription address: %x"),(TUint)this);

LOG_DEBUG(buf);

Replace the LOG_DEBUG with your own logging facility, and put the code snippet into every object's constructor. If you encounter a panic as described above, find the hex value in your logfile, and you know what type of object it is that is not properly freed and thus causes the panic.
