msgbox fails with --gc:arc

[qqtop]

# test.nim
# simplified example to show issue with msgbox if compiled with --gc:arc/orc

import nigui
import nigui/msgbox

app.init()

var window = newWindow()
window.width = 1280 
window.height = 800 

window.onCloseClick = proc(event: CloseClickEvent) =
  case window.msgBox("你想退出吗 ？", " 退出?", " Leave ", " Minimize ", " Abort ")
  of 1: window.dispose()
  of 2: window.minimize()
  else: discard
  
  
proc main() = 
   var postflag = false
   if window.msgBox("Post new record ?", "Post ? ", "Yes", "Abort /  取消 ") == 1:
      postflag = true
   else: 
      postflag = false 

   echo postflag

when isMainModule:
  window.show()
  main()
  app.run()
  

works as expected with nim c -r test.nim
fails with nim c --gc:arc -r test.nim

compiling with -d:useMalloc it says malloc(): unsorted double linked list corrupted

works now (probably was broken because of nim-lang/Nim#17003)

As Yardanico wrote, it works with Nim 1.4.4.
