Fil-C version 0.680 introduces support for ucontext APIs (setcontext, getcontext, etc.) implemented in a fully memory-safe manner. This update ensures that common misuse patterns, such as restoring dangling stacks after thread exit or function return, no longer violate the capability model or cause stack corruption.
Background
The ucontext APIs are traditionally used to implement coroutines and fibers but are prone to memory safety violations when contexts reference freed or invalid stack frames. Fil-C is a capability-based C runtime designed to enforce strict memory safety guarantees.
