The cache is keyed by object + system + target + grafts?; if there’s anything that influences what the object lowers to, changes are the object->derivation mapping is already cached and that other thing will be ignored. That’s a problem generally speaking with using ‘with-parameters’ with parameters other than ‘%current-system’, ‘%current-target-system’, and ‘%graft?’. I wonder if it’s the only thing at play here though. Ludo’.
