[Bug]: uncaught exception of type std::__1::system_error with enabled ThreadSanitizer on quit

[vhlukhov]

Detailed steps on how to reproduce the bug

When utilizing the JUCE Framework with ThreadSanitizer enabled, the application is unable to properly terminate the application.

1. cmake -G Xcode -B Build -DJUCE_BUILD_EXTRAS=ON -DJUCE_BUILD_EXAMPLES=ON
2. Select DemoRunner and enable the ThreadSanitizer
3. Launch the application
4. Quit application
5. The debugger will stop when an error is detected, which will cause std::terminate.

libc++abi: terminating due to uncaught exception of type std::__1::system_error: mutex lock failed: Invalid argument

This behavior is reproduced on all versions of Xcode 15.x. It's hard to tell if it was reproduced on macOS Sonoma earlier versions.

What is the expected behaviour?

The application should close correctly without errors.

I've taken a quick look at this. I can reproduce the issue but it's difficult to know what to conclude.

• It happens on JUCE versions dating back to at least 7.0.0 (I haven't tested anything older)
• JUCE console applications appear unaffected
• JUCE plugins appear unaffected (tested using VST3 in Reaper)
• It happens in multiple Xcode versions (tested with 15.4, and 16.1 Beta)
• The crash occurs after the main function has returned
• No JUCE code appears to be in the stack of any of the threads when it crashes

If it is a fault in JUCE causing the issue it must be something with global or static duration, however having not seen this in the past or heard other reports, given the information above, and that such a crash is normally the result of a threading issue which the thread sanitiser should pick up, and it only happens when the thread snazzier is enabled, I feel the only logical conclusion is that thread sanitiser is somehow at fault?

• It might be nice to confirm this doesn't happen on some older versions of Xcode/macOS. Unfortunately I can't run Xcode 14 versions on my Sonoma machine
• It would also be nice to reproduce the issue with a smaller project, the best I managed was a blank JUCE GUI app for now
