Hi Dave
I also noted such issue playing with the previous
4.3.2-1 and my own built cygfortran.dll, but I thought
was my fault.
It seems a problem of output redirection with dynamic=20
fortran library

if I had=20
./test_program=20
I see the output on the screen but

./test_program > test_output
leave test_output empty.

This did not happened with static linked fortran library.

test case:
------------------------------
      program main
      WRITE(*,*)     'SUCCESS'
      end
------------------------------
