Doesn't mi_atomic_cas_weak_release update tfree in the failure case.
E.g. it is based on:
https://en.cppreference.com/w/c/atomic/atomic_compare_exchange
Have you actually observed this execution hanging execution? On what platform as it could be the atomics are not implemented correctly in that case?

Just double-check the result. I believe you are correct. I mapped the mi_atomic_xxx instructions to a different atomic library, which doesn't have the failure update feature that causes the issue.
