How to get a stack trace from FastMM

I've noticed in the following post that you can get a stack trace out of FastMM to show what appears to be where an object was allocated:

How to track down tricky memory leak with fastMM?

I can't find any information on how to enable this in Delphi 2009, though.

I have set ReportMemoryLeaksOnShutdown to true so I get the basic report, but how do I get the stack trace report?

The internal Delphi version of FastMM doesn't support stack traces.

If you want to log the memory leak stack traces, you have to:

  • download the full version of the FastMM library

  • include it as the first unit in your project:

    program YourProject;

uses
  FastMM4, // <--
  SysUtils,
  Forms,
  ...

  • enable the FullDebugMode option in FastMM4Options.inc

  • set Map file to Detailed in the linking project options (the FastMM_FullDebugMode.dll processes the .map file)

  • add the FastMM_FullDebugMode.dll in your binary (or Windows System32) directory

You can also see this and this for more detailed description, than ulrichb's reply.

And don't forget to enable "Use Debug DCUs" option ;)

In addition, Francois Gaillard presented on CodeRage II a session called Fighting Memory Leaks for Dummies and deals specifically with FastMM. It is listed under the CodeRage II replays at thursday, November 29, 2007, 9.45am - 10:45am.

You may also want to check out Jeremy North's FastMM4 Option setting program. It's just a bit easier than editing the inc FastMM4Options.inc file directly. Here's the link:
