Cubase 7 - JuceDemoPlugin crashing on application close


#1

I frequently get crashes when closing a session in Cubase 7.0.1 when my plug-in’s editor is visible. Crashes are almost repeatable every time if I click on the plug-in GUI and get Cubase drawing stuff in the background. I can repeat the crash with the demo plug-in by clicking inside the GUI and simultaneously quitting the application.

Below is the only interesting part of the crash log. Lines 4 and 16 show as ?? in the debugger i.e. bad memory access.

Cubase 6.5.4 does not have this problem, so I guess the ball is really in Steinberg’s court. Just thought I’d give you all the heads up!

Erm, no… Since the crash is clearly in your destructor (assuming “CSoloist” is your plugin, right?), then I’d say the ball is in your court.


#3

I wish it was! I can confirm that both the editor and processor destructors are called in the correct order before the application quits. This bug is completely reproducible with a clean Introjucer-built JuceDemoPlugin.

The destructor in the crash log is somewhere deep in Cubase land… if you google CSOLOISTExtendedAnalysis you will get several search results relating to Cubase crashes from different vendors.

Looks like OS level messages are being sent to an already deleted instance, or something along those lines.


#4

Ah, I see. Well yep, sounds like Steinberg’s problem then!


#5

Okey. I have similar problem to one described above. The same problems were discussed here:

http://www.juce.com/forum/topic/cubase-freeze-mountain-lion

http://www.juce.com/forum/topic/cubase-mac-crashes-when-closing-more-guis-fast

And I don't think that it's Steinbergs problem, because other vst plugins are destroyed correctly, but not those written in JUCE. The problem occurs in Wavelab too.

I found out, that the bug is related to focus.  I can load plugins and than unload my inserts without any problems. But always last instance of plugin can't be destroyed if I click anywhere inside of plugin window (tested on 32 Cubase 7 MAC) or moving some sliders. 

There's an easy way to make a test. Load JuceDemoPlugin into insert. Than without clicking inside of it - try to unload. Everything works fine.
 

We can repeat action, but before unloading insert - just click anywhere inside of plugin - boom.... Cubase is goin' mad.

We can repeat action another time, but after moving sliders we have to click on main cubase window - so the plugin loses focus. Everything works fine.

 

I found out, that when I set JucePlugin_EditorRequiresKeyboardFocus to 0,  the problem seems to be solved... But of course TextEditors doesn't work properly.


I think we have to loose focus in Editors destructor, but I don't know how to do it... setWantsKeyboardsFocus(false) doesn't work.

 

Any ideas??


#6

Hmm. Very hard to know what cubase could be doing differently just because of the keyboard focus.

All I can think of to try as an experiment would be to try removing the event loop at line 205 of juce_VST_Wrapper.mm, since that's most often the cause of crashes when closing down.. (I don't have cubase 7 installed myself to try this at the moment)


#7

I removed 
 

        for (int i = 20; --i >= 0;)

            MessageManager::getInstance()->runDispatchLoopUntil (1);

 



from code, but it didn't help. 
I tried many things like:



 

    [hostWindow miniaturize:nil];

    [pluginWindow miniaturize:nil];

    

    [pluginView unlockFocus];

    [pluginView setHidden:true];

    

    [hostWindow orderOut:nil];

    [pluginWindow orderOut:nil];

    

Nothing helped.... Is there is any possibility to loose keyboard focus??


#8

How about calling [pluginWindow resignKeyWindow] and [hostWindow resignKeyWindow] before releasing them? 


#9

No it doesn't work.


#10

I have the same problem, but i have also no cubase to test it here. Can I help on any way?


#11

I'm having a similar issue as well on Mac OS X 10.9 and Cubase 7.5.10. Except that removing the plugin will also crash Cubase. This has me really stumped.


#12

Ok, I have installed 7 elements trail and can test it here for 30 days too :-)

Here cubase only crash's if the plugin-UI still is open on cubase exit. If the plugin-UI hidden/closed, Cubase does not crash. Can anybody confirm this?
I have tried a lot of configs, deployment targets and so on - no chance.

Here my complete crash log:

#13

Crazy. If i have 1+n plugins loaded and only one UI is hidden, then cubase also not crash on exit.


#14

I have exactly the same problem right now, Cubase 7 Elements crashes all my JUCE plug-ins when I'm trying to quit a session with the GUI still displayed. I am with Mac OS 10.9.


#15

Same here; every time you close Cubase 32-bit with a JUCE VST plug-in's UI open, it crashes.
 

I've been speaking to one of Cubase's developers, who says:

To pin a Cocoa window to a Carbon window needs to be done correctly and it looks like JUCE doesn't do this correctly.
What I see here is that JUCE is incrementing the reference counter at some point and it never decrements it. That's why Cubase crashes, because the window is destroyed too late when quitting Cubase. 

Note that there was another crash in previous versions of Cubase 7, affecting both JUCE and certain non-JUCE plug-ins, caused by Cubases's premature unloading of the plug-in bundle. That bug is now fixed in Cubase 7.5, and, despite the similar symptoms, unrelated to this one.


#16

There was a ref-counting error which I fixed a couple of weeks ago?


#17

Superb; I'll give this a test, and report back.


#18

 

EDIT: JuceDemoPlugin seems to be working fine now in Cubase 7. Now I just need to work out why my plug-ins are still crashing!


#19

This problem seems to have been fixed in the 32bit VST version, but still occurs in the 64bit version.

 

On OSX 10.9 with Cubase 7.5 and JUCE 3.2.0:

Add juceDemoPlugin to an empty project, click the GUI to give it focus, then quit Cubase (leaving the GUI open), it'll crash.

 

Any chance this'll be fixed too?


#20

On 64-bit it doesn't use Carbon, so the stuff discussed on this thread won't apply.

Most likely you're talking about the old problem of some hosts not allowing time for the message thread to run after deleting an NSWindow, which causes a crash after the plugin has been unloaded from memory. As discussed many times on the forum, we can't do much about this from the plugin side of things.
