When I was on CT 4.8 I've created an example short Daemon app.
It was all OK on CT 4.8.
I've made a clone of Dev Virtual Machine and on that clone made an upgrade to CT 4.9
Daemon app compiled on CT4.9 has memory leaks - the same app, the same sources - just IDE has changed.
Compiled with DEBUG and run then gives: [hit Ctrl+C after 5-6 seconds]
msap@lubuntudev-1-0:~/Desktop/msapTemp$ ./msapTemp --run
^CHeap dump by heaptrc unit

Did you run Typhon as Root?

Yes. I'm starting CT Center using gksu, and then I always start Typhon IDE from CT.
The compiled app is run from Terminal as a normal user.
My behavior is identical with CT4.8 and CT4.9 - only IDE has changed.

Unfortunately NO LUCK !
Typhon 5.0 still gives memory leak.

On my first post I attached complete ZIP package of the project. You could try it yourself for better tests.

Of course - thank you!
In the internal Daemon log there is something strange.
After I hit Ctrl+C to stop the Daemon you see:
"Failed to start daemon TDaemon1 : Access violation"

The LOG from CT4.8 after status: Stopped has another one and last tick with Date and Time - it's from Execute procedure of Daemon.

If you want me to do more tests please post a message - I have a Virtual Machine box for development so I can do anything.

I've made a diff using files: daemonapp.inc and daemonapp.pp and the only difference between CT4.8 and CT5.0Beta are in
one line in file daemonapp.pp on line 136
jk@ubuntu1:~/Pulpit$ diff -a -s daemonapp_48.pp daemonapp_50.pp
136c136
<     Property CheckPoint : DWord;
---
>     Property CheckPoint : DWord read FCheckPoint;

I've searched lazDaemon sources for bugs or something - there are no bugs in this files, besides there are no differences.
All source code seems to be OK.

Any news about this bug?
Present Lab 5.0 beta version still makes a memory leak.
For development I still must use v4.8
