I guess the following wording is quite close to the one you desire:
@ChangeLog:
* Fixed fibers switch-over to prevent JIT machinery misbehaviour. Trace
recording is aborted when fiber yields the execution. The yield
occuring while the compiled code is being run (it's likely a function
with a yield underneath called via LuaJIT FFI) leads to the platform
panic (gh-1700, gh-4491).
