How to get a stack trace from FastMM

Question

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?

Answer 1

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
