The crash seems to be in CoreText. CoreText is embedded/linked in Messages, Spotlight, Springboard, etc. CoreText is written in C.
The fix would be to rewrite CoreText in a memory safe language like Swift. This would be “hard”. Or put CoreText in an XPC container. This would both be “hard” and result in terrible performance.
For more details on how hard C, memory management, systems programming, and operating system development is please refer to your local copy of Modern Operating Systems by Andy Tannenbaum.
