What version of gfortran are you using (i.e. exactly which binary did
you download)?

I'm not sure about the crash, but I can say that you will never get
the output from a write statement inside the Fortran code to go to the
IDLE prompt or PyScripter's window. They are not real terminals and do
not capture text going to the process's real STDOUT file pointer. They
simply change the sys.stdout object to capture text printed from
