If I understand the question: * With 34c3eed615, "pr12644.rkt" can compile and run.
* With d29df205f7, "pr12644.rkt" fails to compile. * A bytecode form of "pr12644.rkt" compiled with 34c3eed615 can still run in d29df205f7, because run-time support for "pr12644.rkt" didn't change. * When you tell `racket` to run "pr12644.rkt", it will use a ".zo" for each of "pr12644.rkt" and its dependencies as long each individual ".zo" file has a newer timestamp than its ".rkt" file. That is, the only timestamp comparisons are on individual ".rkt" and ".zo" pairs. * When you tell `raco make` to build "pr12644.rkt", it checks dependencies (via ".dep" file) and compares a ".rkt" file's timestamp against the times of all of its dependencies, instead of just checking individual ".rkt" and ".zo" pairs. That's why a `raco make` in d29df205f7 tries to recompile "pr12644.rkt".
