When I run the program below, and feed it a file with less
than 10 records (just a list of reals), i.e., the 'end=2'
redirection in the read statement should be followed,
generates an internal error on a linux pc (i686-pc-linux-gnu)
about recursive library calls not being allowed (see below).
However, when I remove the 'close(78)' line the internal
error mysteriously disappears.
On a hp pa-risc machine (hppa2.0w-hp-hpux11.11) this program
just runs as expected.

gfortran -dumpversion:
GNU Fortran 95 (GCC 3.5-tree-ssa 20040119 (merged 20040102))

          n = n + 1

          write(6,*) 'end reached'
 3    continue

      close(78)

      end
