[$] Fil-C: A memory-safe C implementation

Fil-C is a memory-safe implementation of C and C++ that aims to let C code -complete with pointer arithmetic, unions, and other features that are oftencited as a problem for memory-safe languages - run safely, unmodified.Its dedication to being "fanaticallycompatible" makes it an attractive choice for retrofitting memory-safetyinto existing applications. Despite the project's relative youth and singleactive contributor, Fil-C is capable of compiling anentire memory-safe Linux user space (based onLinux From Scratch),albeit with some modifications to the more complex programs. It also featuresmemory-safe signal handling and a concurrent garbage collector.
