Ben Thomas (enkidatron) (Dec 19 2024 at 04:03):The optimizer seems to not like my style of recursion or something. roc build --optimize day17.roc && ./day17 says it cannot find an answer while roc dev day17.roc gives the correct answer. Are there known cases of the optimizer changing a programs output?
Brendan Hansknecht (Dec 19 2024 at 04:04):There is #bugs > opportunistic mutation bug with "--optimize"?
Ben Thomas (enkidatron) (Dec 19 2024 at 04:12):Thank you! I will check the #bugs channel next time
