It does not detect memory leaks stemming from memory not allocated via  
FPC code. A lot of Mac OS X framework routines return pointers that  
you have to retain/release in a balanced way.

It works only for memory allocated by the fpc heap manager, so a winapi CreateWindow 
call, or a gtk gtk_button_new call would create an undetected memory leak, if the 
returned handle/pointer is not release properly.

Why not just use unit heaptrc?



Quoted from that page:

The HEAPTRC unit can be used to debug your memory
allocation/deallocation. It keeps track of the calls to
getmem/freemem, and, implicitly, of New/Dispose statements.

When the program exits, or when you request it explicitly. It
displays the total memory used, and then dumps a list of blocks
that were allocated but not freed. It also displays where the
memory was allocated.

If there are any inconsistencies, such as memory blocks being
allocated or freed twice, or a memory block that is released
but with wrong size, this will be displayed also.

The information that is stored/displayed can be customized using
some constants.

Works very well.

You sometimes get loads of output highlighting several memory leaks. The
backtrace information doesn't always lead tot he exact location where
the memory leak was caused. That's the "hit and miss" I mentioned.
Sometimes the backtrace is correct and sometimes it is not. Also
sometimes you fix one memory leak and suddenly our heaptrc output report
that half the memory leaks are fixed.

Anyway, as I said, I enable heaptrc for all my coding projects so that I
detect memory leaks as soon as they are introduced. This greatly reduces
my time in find them, because I know what code I was working on.
Obviously at app deployment, I disable heaptrc.

Yes, my memory leak was not about allocated blocks but rather about
correctly calling release for NSMenu, NSMenuItem and other Cocoa
objects.

Thanks, I'll try the Tiburon SVN version of Indy then, but if it doesn't

Well, if one checks out the latest Indy SVN sources from

svn://svn.atozed.com/indy/indy10/trunk

the latest revision is 3778 (last update was in April 2009) there is no 
way to compile it for FPC/Lazarus.
The FPC related README file is the same as for the 2007 10.2.0.3 FPC 
only version and the steps are not working here because there are no 
such directories in the trunk.
There are some Makefile.fpc in a few directories, but all of them lists 
10.2.0.1 in them as a version (in \Lib\System\IdVers.inc it says 10.2.3).


There is a \Lib\indymaster-Makefile.fpc but it gives
"
make -f indymaster-Makefile.fpc all
indymaster-Makefile.fpc:1: *** missing separator.  Stop.
"

In short I did not find a way to even compile the latest Indy source for 
FPC/Lazarus from their SVN.


Maybe someone more knowledgeable could make a try at it and suggest some 
steps that work.
As of now, only the old 2007 10.2.0.3 FPC only, non-merged Indy can be 
compiled for FPC/Lazarus

Yes and no. It is dead because it was succesful, and backmerged into
mainline Indy. 


However Indy merged a big branch (for Tiburon support) back into the
mainbranch, so that could have upset minor things, like the Lazarus project

So the rough core is working, but the "polishing" hasn't been redone

It's basically a library of common parsing functions combined to produce a
fully functional parser. Haskell and C++ has this kind of library, so I'm
looking for a Pascal one. It could help so that one doesn't have to write a
parser from scratch, instead he just needs to choose correct parsers to fit
in his grammar.
