What happens when there's a bug in bash? Same thing. init is not the only component or source of complexity in the old way. Sometimes the problem will be in the script, sometimes it'll be in the thing that runs the script. Initscripts are vastly more complex than systemd service definition files (and the latter is declarative rather than procedural). Systemd pushes some of the complexity down the stack, and that is a reasonable choice. There will be more bugs in systemd than init and bash (or ash or dash), simply based on age and maturity of the respective projects. There's complaints to be made about systemd, but I don't find this complaint compelling, at all. I think moving from procedural programs that are sometimes hundreds of lines long to declarative config files that are never more than a couple dozen is an overwhelmingly positive thing.
