Cannot debug FireMonkey applications on OS X 10.7.3 with XE2 Update 4

Short recap for people that came here via the internet search.

On some installations Delphi can't debug FireMonkey applications on OS X. Symptoms: Delphi starts loading the Debug desktop and then locks. Pressing Ctrl+C in the PAServer stops the PAServer and unfreezes the Delphi. The problem was observed with Delphi XE2 Update 4 and OS X 10.7.3.

Longer description is attached below.

I have a brand new Mac Mini (mc815z/a model - i5 2.3 GHz/2GB/500GB/Nvidia Intel HD Graphics 3000). It came with OS X Lion (10.7) which I upgraded to 10.7.3.

On my main computer (Windows 7 64-bit) runs Delphi XE2 Update 4. I've installed platform assistant from setup_paserver.zip (15.656.945 bytes). It installed Java first (Java for Mac OS X 10.7 Update 1). I'm starting PAServer via paserver.command and it seems to be working fine. PAServer says it is version 1.0.2.

Then I've set up a remote profile and it works fine (Test Connection reports success).

When I run (with debugging) a FireMonkey project (I tried various Sample projects and also fresh, minimal FireMonkey application), Delphi starts switching to the Debug layout and then freezes. PAServer reports:

Process Control Server Started pid 343 exe build Jan 15 2012

sentinelFunc 345

[The number in the second line is different every time I try to debug the program.] Nothing happens then. I can kill the PAServer with Ctrl-C and that unfreezes the Delphi. Delphi then reports error:

Debugger Assertion Failure: "obj" in ..\win32src\rproxy.cpp at line 663

Package file seems fine to me:

package contents

I'm logged on locally as a user in the Admin group.

I can start the application from /Users/primoz/Applications/Embarcadero/PAServer/scratch-dir. No problems there. Run without debugging in Delphi also works. The problem only appears if I try to debug my app.

EDIT: This seems to be a problem with my Delphi installation. I tried the same from my notebook (also running XE2 Update 4) and it works just fine.

EDIT: It seems that this is related to my debug desktop. When I changed debug desktop to be the same as the edit desktop, problems disappeared.

EDIT: This problem only appears if I have 'Thread Status' window visible on the debug desktop. Furthermore, this is related to my Delphi installation - the other computer I tested on works fine with 'Thread Status' window visible.

Solution

  • This problems is related to the Thread Status window. If you experience locking while debugging on OS X, remove Thread Status from the Debug desktop.

    Strangely, some XE2 Update 4 installations are working quite fine with Thread Status visible, and some are not.
