Compiled with OSX 10.6.8 - XCode 3.2.6

Hard to tell, but it could be that the host is passing a null pointer to SaveState(), and that's making Apple's own SaveState() method crash.

You could try adding a check to prevent that:

Code: Select all

    ComponentResult SaveState (CFPropertyListRef* outData)
    {
        if (outData != nullptr)
        {
            ComponentResult err = JuceAUBaseClass::SaveState (outData);
..etc


But it could also be something inside Apple's SaveState() that's crashing for some other reason. Or perhaps the whole object is dangling. Can't tell from that stack trace.

thanks, but does not help.

trying now with compatibility SDK 10.4. but i'm not optimistic

[chkn]

hopefully this is (not) a bug in auval .... doing some compatibility checks from a fresh 10.5 installation
10.4. unable to compile

[ckk]

Can't say what's the reason for the crash, but we're using 10.5/10.5 as base/deployment SDK which builds non-crashing plugins. I didn't test with auval but the plugins crashed in different hosts.
So if that's an option it might be the easiest solution.

edit: forgot to mention, this was more than a year ago and we haven't changed the sdk since then, so it might be another cause for the crash in your case.

thanks for the info!
just stumbled over this post (last sentence) mmhhhh...

Just compiling with 10.5/10.5, i get the font-bug in Logic again, how can that be Jules?

[chkn]

OK, with 10.5/10.5 it WORKS IN 10.5 BUT the destroys the font in 10.6!

[chkn]

it seems that fonts which the "bold" attribute, don't have the problem.

[chkn]

i modified the juce demo, to reconstruct the problem.
The only thing you have to do is set Base SDK And Target SDK to 10.5.

I took a look. This is not the same bug as last time, this is something completely different.
The problem lies somewhere in the old font code (Cocoa).
I had no hand in writing that code so I won't be fixing this problem in my own free time.
If you'd like me to look at it further, shoot me a PM and maybe we can work something out.

[chkn]

thanks for your offer, i just made a test, with the latest April check-in (before the big one), and it works (with 10.5 base sdk), so this must be a new issue

[chkn]

*bump*

[chkn]

In the current state, its just impossible to create AU-Plugins which are compatible with 10.5/10.6.
To be compatible with Logic under 10.5 you need to compile against base(!) sdk 10.5 , but this destroys the font rendering.
