When dummy argument "wait" of intrinsic "execute_command_line" is not present, it's treated as ".false."

[psteinfeld]

Here's a program that shows the problem:

program bug
  call inner("echo hello")
contains
  subroutine inner(cmd, wait, exitstatarg, cmdstatarg, cmdmsgarg)
    character(10) :: cmd
    logical, optional :: wait
    integer, optional :: exitstatarg, cmdstatarg
    character(128), optional :: cmdmsgarg
    integer :: localvar
    call execute_command_line(cmd, wait, exitstatarg, localvar, cmdmsgarg)
  end subroutine
end

@yi-wu-arm, please take note.
When I compile and executes this program, it behaves as if the wait argument has the value .false.. It's supposed to act as if the value is .true..

Will take a look tomorrow morning

This is caused by isStaticallyPresent(wait) will return true when the value is optional, a patch fixing this will come up soon.
