JclLastExceptStackListToStrings produces an empty string list

Question

I've installed JCL into Delphi 2010. In the following code

try
  raise Exception.Create('Error Message');
except
  on E: Exception do
  begin
    ResultStatus := JclLastExceptStackListToStrings(sl, True, True, True, True);
  end;
end;

Also I have this call in the initialization section:

initialization
  JclStartExceptionTracking;

ResultStatus is false and sl is empty. I have set options to generate map and .jdbg files. Other functions, like ProcByLevel work fine. Is there something else I need to do to make JclLastExceptStackListToStrings work?

From JclDebug.pas file:

It would be good if you came back and said what happened, and accepted the answer that worked! — Warren P, Apr 11 '12 at 20:32
Unfortunately I don't know the reason. I reinstalled everything (including IDE) and started a new project. So it might have been a number of reasons, but I didn't have time to find what it exactly was. — Max, Apr 16 '12 at 18:06
I get the same behavior while using XE2. I find that I am 1 exception behind. meaning I get results on the second pass. — Troy Harris, Jun 04 '13 at 15:30

Try calling

JclStartExceptionTracking;

at the very start of your application.

[Edit]You already are. Then I'm currently out of suggestions. [/Edit]

He's calling it in the initialization section. Would you have him call it earlier, or later? If earlier, how? – Rob Kennedy Jan 16 '11 at 19:04
He hadn't mentioned that yet when I posted this answer (check the edit log). I'll update my answer to avoid confusion. – Paul-Jan Jan 17 '11 at 18:30

I solve this problem in Delphi XE 1.

open Project Options menu
open Delphi Compiler tree node
select Linking tree node
enable Debug Information checkbox

I've been stuck with this problem for a few days. JCL stack tracking was working with my programs and I was able to pinpoint the error location. Somehow it just stopped working.

Then I worked with JCL's demo to see if it is working without any problem. It worked very well. I set all the project options same with the demo and yet my program did not dump stack while the demo was working everytime.

Suddenly I noticed that the only difference between my program and the demo is CPU architecture. Demo is 32 bits and my program is 64 bits.

I compiled the JCL demo as 64 bits and it stopped working too. It is working only with 32 bits code. Not 64 bits.

Unfortunatelly my program needs 6-7 gigabytes of memory and I cannot use the 32 bits mode. I suggest to use Eurekalog since it is working for both architectures.

I use:

JclStackTrackingOptions := [stStack, stExceptFrame, stRawMode, stAllModules, stStaticModuleList];
