DemoRunner 7.0.3 - if you run the Multithreading Demo, just let the default initial screen of moving balls run for 5-10 minutes, DemoRunner crashes.
This was on MacOS Mojave 10.14.6. Crash log attached:
crashlog.txt (78.9 KB)
I then took the PIP of the Multithreading Demo and ran it on Xcode/Mojave. It didn’t crash as quickly, but a few hours later it hit a SIGABRT:
libc++abi.dylib: terminating with uncaught exception of type std::__1::system_error: mutex lock failed: Invalid argument
Same issue here on macOS Ventura 13.5.2 (Mac mini M2 Pro), using JUCE 7.0.4 or 7.0.5.
I tried to update to 7.0.6, 7.0.7 or the latest develop (5e52056b9), but I have a different crash (assertion fail) happening right away when loading the MultithreadingDemo:
I use similar code in my plugin, which obviously reproduces the same behavior.
Is there an alternative to the MessageManagerLock that would work properly until this is fixed ?
Just to keep you posted I looked into this yesterday. I believe I’ve got a solution but it probably won’t be merged until sometime next week,
Thanks for reporting.
Oh that’s perfect!
We never release on a Friday anyway 
Have a good weekend!
