nim c --gc:arc --exceptions:{setjmp,goto} incorrectly handles raise; nim cpp --gc:arc is ok

Example

  type MyExcept = object of CatchableError
  proc gun()=
    try:
      raise newException(MyExcept, "some msg")
    except Exception as e:
      echo "caught in gun"
      raise e

  proc fun()=
    try:
      gun()
    except Exception as e:
      echo "caught in fun"
      echo ("caught", e.msg, e.name)
    finally:
      echo "in finally"
  fun()

Current Output

nim c --gc:arc --exceptions:setjmp main.nim
nim c --gc:arc --exceptions:goto main.nim

in finally
/Users/timothee/git_clone/nim/timn/tests/nim/all/t0900.nim(74) t0900
/Users/timothee/git_clone/nim/timn/tests/nim/all/t0900.nim(68) fun
/Users/timothee/git_clone/nim/timn/tests/nim/all/t0900.nim(61) gun
Error: unhandled exception: some msg [MyExcept]

Expected Output

nim c main.nim
nim cpp main.nim
nim cpp --gc:arc main.nim

caught in gun
caught in fun
("caught", "some msg", "MyExcept")
in finally
