audioOutputExample crashes in El Capitan

I’m working in an audio application for macOS. After updating to openFrameworks 0.11.2 the app crashes at startup when running in 10.11 El Capitan.

The error seems related to ofSoundStream.

When building and running audioOutputExample from the examples folder (to test ofSoundStream) I get this error in El Capitan:

I’m building with xcode 11.3.1 in macOS Mojave.
Deployment target in xcode project is 10.9

When using openFrameworks 0.11.0 both the app and audioOutputExample run with no errors in El Capitan.

Any ideas how to solve this ?
Has openFrameworks 0.11.2 dropped support for older systems ?

I think I’ve found cause of the error. If I replace rtaudio.a (in openFrameworks 0.11.2) with the one distributed in openFrameworks 0.11.0 I can build audioOutputExample and run it in OS X 10.11 without crashing.

It seems rtAudio in openFrameworks 0.11.2 is compiled for a newer target.
