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))

It does not happen on powerpc-apple-darwin either, I have not tried i686-pc-linux-gnu yet.

Confirmed on i686-pc-linux-gnu.

Here's a slightly reduced version with hardcoded input filename.
Runs fine with g77, but crashes with gfortran.
If the input file is empty one gets a segfault instead of the error message.

======================================
      program foo
      integer i

      open(78,file='data.txt')
 1    continue
          read(78,*,end=2) i
          write(6,*) i
          goto 1
 2    continue
      close(78)

      end
======================================
