[Bug fortran/40576] [4.5 Regression] Endless loop in internal write

I can confirm the regression is from the I/O patch, but not related to format
caching. The test case is looping here:

(gdb) bt
#0  mem_alloc_w () at ../../../gcc45/libgfortran/io/unix.c:579
#1  mem_write (s=0x601c00, buf=0x7fffffffdd10, nbytes=16)
    at ../../../gcc45/libgfortran/io/unix.c:622
#2  0x00007ffff7dc780f in swrite () at ../../../gcc45/libgfortran/io/io.h:70
#3  sset (s=0x601c00, c=<value optimized out>, nbyte=16)
    at ../../../gcc45/libgfortran/io/transfer.c:2869
#4  0x00007ffff7dc8f0f in next_record_w ()
    at ../../../gcc45/libgfortran/io/transfer.c:3002
#5  next_record (dtp=0x7fffffffdfa0, done=1)
    at ../../../gcc45/libgfortran/io/transfer.c:3058
#6  0x00007fffffffdfa0 in ?? ()
#7  0x0000000000000000 in ?? ()

Janne, will you look at this as well please. We are not catching the EOF
condition.
