EXC_BAD_ACCESS in Signaling thread

I've been trying to get the AppRTCMobile example to run on MacOS (there's a version meant to run on macOS) and, after getting it to compile, started running into this issue:

Signaling Thread 0x0x4 (18): EXC_BAD_ACCESS (code=EXC_I386_GPFLT)

Stack trace:

This happens when the signaling thread is instantiated and passed to CreatePeerConnectionFactory.
