| Jun 16, 2017 at 10:49 | comment | added | Jules | One additional complexity that you need to be aware of in compiled vs interpreted runtimes relates to this sentence in your answer: "(Tracing) garbage collection usually starts by walking the call stacks of all threads that are currently running." My experience of implementing GC in a compiled environment is that tracing the stacks is not enough. The starting point is usually suspending the threads for long enough to trace from their registers, because they may have references in those registers that haven't yet been stored in the stack. For an interpreter, this isn't usually ... | |

The Boehm GC is an example of this used in real life programs. | |
