Can you minimize it further, please?

codehz commented 3 years ago

I think it is related to https://github.com/nim-lang/Nim/issues/16847 Because when I try to expand the macro manually, the crash is also disappear...

proc typeIdStorage[T](): var TypeId =
  var storage {.global.}: TypeId
  return storage
Araq commented 7 months ago

Why shouldn't it?
