Works with ORC (as of writing)

• https://github.com/nim-lang/irc - wrong sink parameter passing

---

Won't work in arc without changes in the libraries:

• https://gist.github.com/Yardanico/5a9f7e9842101443ebf662c58340f406#gistcomment-3289689:
  • https://github.com/brentp/hts-nim doesn't work
  • https://github.com/brentp/mosdepth doesn't work because hts-nim doesn't work

---

A bug or not yet sure:

• https://github.com/trustable-code/NiGui - [ARC] Incorrect sinking of an argument?
• https://github.com/nitely/nim-regex - [ARC] ICE with static objects
• ARC: deepCopy in new runtime feature missing, do we have alternatives?:
  • https://github.com/PMunch/nim-persistent-vector: because of deepCopy here
  • https://github.com/mratsim/Arraymancer: known, issue here
  • https://github.com/Vindaar/ggplotnim: partly because of the above two, and also because of a similar thing regarding deepCopy
  • https://github.com/NimParsers/parsetoml: uses deepCopy too
• nimsuggest - compiles if you put ~10 {.nosinks.}, but fails for the first nimsuggest test.
• https://github.com/PMunch/nimlsp - doesn't work as it depends on nimsuggest
• https://github.com/cheatfate/nimcrypto - ARC codegen bug with inline iterators
• https://github.com/oprypin/nim-random - ARC codegen bug with inline iterators
