When using ThreadObj Intermittent error

[rodemp]

I tested in Win 7 32bit

ahk:=ThreadObj("F2::MsgBox(2)")
F1::MsgBox(1)
F5::ExitApp

there is a problem that the process itself stops when it is executed repeatedly

but there was no problem with AhkThread using dll

if the process is stopped with ThreadObj, the exit code 3489660927 is displayed when it is forcibly terminated.

sometimes an error code 3221225477 appeared.

Could not reproduce it, also ahk.ExitApp() does not cause any problems.
