Description
I don't own any Apple Silicon machines. I build my program on GitHub Actions which builds with:
Building with Apple clang version 15.0.0 (clang-1500.0.40.1), 3 cores
Building on MacOS Brand Apple M1 (Virtual)
The code:
Returns a nullptr when passed a valid json string (which was retrieved from another otio::Timeline->to_json_string()).
It seems it is a compiler issue (or a very subtle bug on OTIO).
The code works perfectly on macOS Intel, macOS M3 with Intel build under Rosseta2, Windows and Linux.
Optional
Environment
Operating System: macOS Sonoma - M3 chip (Built on GitHub Actions M1 build).
OTIO version: v0.16.0
Imath version: v3.19
Python version if appropriate: N/A
Reproduction Steps
Binary reproduction (for the lazy one):
https://sourceforge.net/projects/mrv2/files/beta/mrv2-beta-Darwin-arm64.dmg/download
Source code reproduction (cannot verify):
I've created a small stand-alone test which I am unable to test as I don't own an M1/M3 combo. You should try to compile it on an M1 box and run it on an M3 one to see if it fails.
If it fails, but it should allow you to hopefully reproduce the issue (and fix the OTIO issue or report the clang bug to Apple):

Log output if appropriate
See the output of my program when the user tried to run it on an M3 machine:
