Sporadical AU plugin issue with juce::OSXTypeface::getGlyphPositions

MacOSX and iOS
1

Hello everybody.

I have an issue that is difficult for me to track down since it only happens sporadically and only in the AU version of my plugin on OSX. I would really appreciate any hint that points me in the right direction to fix it.

From what I see in the crashlog it seems that it caused by a component that I have subclassed from juce::ComboBox. During paint a lot of AppKit stuff is done but in the end something goes wrong in juce::GlyphArrangement::addCurtailedLineOfText and finally juce::OSXTypeface::getGlyphPositions.

The only two suspicions that I have at the moment are:

  • Maybe the String in the ComboBox item is not a valid UTF8 String. But from what I see this would have been rejected in the String class before and I do not see combobox strings that would cause a problem here.
  • Maybe it is a multithreading issue with loading the Font? But why would this only happen on OSX? And I am creating the Typeface with createSystemTypefaceFor in the constructor of my LookAndFeel instance.

Any ideas? And here the crashlog - sorry for the long post.

Any ideas? Similar experiences? I am lost there …

Just got the same issue (in a vst, with the latest tip of the develop branch). Any idea what might be the cause?

Have seen the same recently using the latest Master branch and AU plugins. Happens so sporadically that I haven’t managed to find the root cause… but good to know I’m not the only one! I am using a custom font stored as binary data, in case that matters.

I am also having the same issue with a custom subclass of juce::ComboBox and a custom font stored as binary data. Was this sorted yet?

Are you using a recent version of JUCE? I fixed a couple of issues to do with text rendering on macOS in the last few months:

If you’re not using the latest version of JUCE, please try updating and see if the issue persists. If it does, please provide a stack trace at the point of the crash. If you’re able to test with Address Sanitizer and provide its output at the point of the crash, that will help us to track down the issue more quickly. Providing a small sample program that demonstrates the problem would also be very helpful.

Thanks, I’m a couple of months behind these changes. Will update and share the results if needed.
