Description

As Pierre Le Riche describes in his document for using FastMM with BCB, a patch is required to _exit to correctly close down the memory manager. Without this, FastMM can't check memory leaks in BCB applications, which is a real shame.

This hasn't been done in BDS2006.

Steps to Reproduce:

1: Create a new C++ Builder VCL Forms Project

2: Add the following lines of code to the beginning of WinMain function.

ReportMemoryLeaksOnShutdown = true;

malloc(1000);

3: Build and run the application.

4: Close your application

4:What SHOULD happen...
FastMM displays a dialog indicating a memory leak (This does happen in Delphi W32 projects)

5: what DOES happen
No dialog is displayed.

Workarounds

None

Could you provide a URL to the documentation by Piere that you describe. Also some steps to duplicate are required to get a bug report opened.

Would it be possible for an update of when could this be solved, or if it won't be fixed, is there any technical or other reason? It's been over 3 years and the original poster even provided a patch. Maybe this has just been labeled as not important to fix, but still... it's quite a nice functionality to have (work's on Delphi, just not on C++).

It's now almost 5 years later, XE has just been released and it *still* has this bug on it. Any hope for the next Patch?

Unfortunately, this issue is still open. In fact, I also reported this issue 2 years ago...
I think that this limitation must be described in release note and Online document etc...

CB XE2 UP4 - Still doesn't work (almost 7 years later)...

I've added Pierres FastMM BCB support file (reqiured for BCB5/6) as an attachment. This contains the documentation.

I've also added steps to reproduce.

Would this option interfere with CodeGuard when enabled?
