------- Comment #2 from jvdelisle at gcc dot gnu dot org 2007-07-17 02:25 ------- Under Cygwin we get:
$ ./a.exe At line 4 of file test.f90 (unit = 29, file = '') Fortran runtime error: File 'con' already exists con is a reserved device name from MS DOS: See http://www.tcs.org/ioport/jul98/driver-3.htm Under cygwin, if I just try to cat to con: $ cat test.f90 | con -bash: /home/Jerry/bin/con: Bad file descriptor This problem has nothing to do with gfortran. I am afraid you will have to edit and change the name to something other than 'con' Even if I try to edit a file named con.f with vi it locks up vi. Unless someone has a better idea, I suggest closing this bug as invalid. How difficult is it to change that name from 'con' to something else? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32784
