3011 :: diagnosing GC safety warnings

  I have a nice long train of GC warnings, with the topmost one:

  
  /home/zax/.nimble/pkgs/magister-0.16.5/magister/game.nim(97, 6) Warning: 'initAvailabilityGame' is not GC-safe as it calls 'launchWorkers' [GcUnsafe2]
  Run

  However, I can't see any global variables being accessed in that proc. The only thing even slightly unusual about it is that it's forward-declared. How can I tell what the variable being accessed in launchWorkers is?

  Annotate the forwarded proc with {.gcsafe.}.
