I have a problem with cygwin gfortran 4.3.2 20080827 on cygwin-1.7. Text written to stdout (unit 6) is lost when redirected. The problem goes away if I add a "close(6)" statement, so the buffer may not be flushed properly. I don't see the problem with vanilla gcc-4.4.0 or gcc-trunk, compiled from source. These versions still use static libraries, so I am unsure if the problem has been fixed, or if it is due to the patches in the cygwin version of 4.3.2. Also, the problem doesn't occur with cygwin-1.5. $ cat j.f90 write(6,*) 'hello' end $ gfortran-4 -o j.exe j.f90 $ ./j hello $ ./j > j.txt $ cat j.txt $ cat j-close.f90 write(6,*) 'hello' close(6) end $ gfortran-4 -o j-close.exe j-close.f90 $ ./j-close hello $ ./j-close > j-close.txt $ cat j-close.txt hello -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
