That'd be when you use lld as a library from a host program, instead of using lld as a standalone executable. lld is tricky in that respect, as it fairly heavily uses global data structures (you can't have two lld linking invocations running in separate threads at the same time), and those structures need some care taken to reset them properly between each run.
