    <p>After many years of working on a general-purpose C++ library using the Microsoft MSVC compiler in Visual Studio, we are now porting it to Linux/Mac OS X (pray for us). I have become accustomed and quite fond of the simple memory leak detection mechanism in MSVC:</p> <pre><code>#ifdef DEBUG #define _CRTDBG_MAP_ALLOC #define NEW new( _NORMAL_BLOCK, __FILE__, __LINE__) #include &lt;stdlib.h&gt; #include &lt;crtdbg.h&gt; #else #define NEW new #endif </code></pre> <p>Every memory allocation is done using this NEW macro. Whenever a process using our library terminates, any memory leaks (blocks that have not been de-allocated) are reported on the console along with the file and line # where the memory was originally allocated.</p> <p>The part about this that I like is that I don't have to actively "run with performance tool" or otherwise indicate that I am looking for leaks. Leaks are reported to me in the regular course of development, every time a process terminates.</p> <p>Now that we are moving to the GCC world, I find that the memory leak detection tools, many of which are quite sophisticated, require that I explicitly indicate that I'm in leak hunting mode. My IDE is Xcode and I've looked into some of the allocation/leak detection tools (like Instruments and MallocDebug) but I admit I haven't spent the time to get my head around them fully yet. I keep getting put off by the fact that I actually have to specify that I'm looking for a leak ahead of time, instead of being alerted to it automatically.</p> <p>I am using Xcode 3.2 and I hear that there's now nifty integration with a static analysis tool, but again I haven't looked into this. I'm looking for some idea of what my options are. Is there a comparable mechanism built into GCC and/or Xcode? Is there a simple third-party library or tool that performs the very basic functionality that I know and love? Or should I suck it up and learn the new way of doing things?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
