  I bet you compiled your app with -d:release, so that error was hidden before Nim 0.20.

  Just compile with -d:danger now, and it will be hidden again.

  No not serious, better search for the reason of that bug.

  You've successfully broke the compiler :) Can you file a bug report on github for this? Preferably with a code snippet that could reproduce the problem.

  @Stefan_Salewski From the stacktrace it appears that this is a compiler bug, not a bug with the user's code.

  i use includes. if replace the include with the file contents it compiles fine. (but int.high as enum value throws error) (include throws error even if int.high not used)

  Example

  nim.cfg

  --define:channelenabled

  channelhandler.nim:

  type mainChannelIntCodes = enum

  mciHello = 1, mciQuit = int.high - 1 # int.high gives error too

  proc handlechannel*(): <<<<<<<<<<<<<<<

  case inbox.msg: of int(mciQuit): app.quit()

  appbase.nim:

  template mainLoop*T=

  when channelenabled: handlechannel() <<<<<<<<<<<< eventhandler #! YOUR event handler that handles inputLoopEventFlowVar

  main.nim:

  import appbase when channelenabled: include channelhandler.nim

  app.mainloop:

  >calls channelhandler() here<

  case inputLoopEvent.evType:

  Yepp, recompiling Nim with danger made it >;)

  narimiran commented 20 hours ago on github: ...if your nim was bootstrapped without -d:danger flag. I.e. if you need a workaround until this is fixed, bootstrap Nim with ./koch boot -d:danger.
