The error is the fault of the mingw headers being incorrect for exec*, but makes no difference. (SuSv3 whines at length about why the headers need to be as they should be.) See the $ before the [ there? That's a shell prompt. The program already ended, but the output is a little scrambled (which seems to happen a lot when there are child processes of late).
