After writing to or reading from an unformatted file an attempt to read from
standard input causes a crash with "Fortran runtime error: End of file".
I have gcc version 4.1.1 20060525 (Red Hat 4.1.1-1) on Fedora Core 5. My system
is x86_64 but I have seen the same problem on i686.
Sample Code
----------------------------------------------------------
PROGRAM test
INTEGER :: n, ii(10)
print *, '1: enter a number.'
read *, n
ii(:) = n
OPEN(unit=5,file='binary.dat',form="unformatted")
WRITE(5) ii(:)
CLOSE(5)
print *, '2: enter a number.'
read *, n
OPEN(unit=5,file='binary.dat',form="unformatted")
READ(5) ii(:)
CLOSE(5)
print *, '3: enter a number.'
read *, n
END PROGRAM test
---------------------------------------------------------
Either the second or the third read statement (if the second is commented out)
will cause the "Fortran runtime error: End of file" crash.
