This is a bug report for perl from warren.dodge@tektronix.com,
generated with the help of perlbug 1.34 running under perl v5.8.3.

I just ran into something I did not expect. I am not very familiar when the
workings of dbm files so that may be the problem.

I had build some dbm files on solaris 8 using a loop similar to this

  dbmopen %ARRAY, "array" , 0666  or die "can not open >array<\n";
  foreach $key ( keys %array )
  {
    $ARRAY{$key} = $array{$key};
  }
  dbmclose %ARRAY;

I then went over to linux with the same version of perl and ran the script to
make them again and got the following.

can not open >array<


I removed the files and built them from scratch on linux and that seemed to
work.

I then went back to solaris and ran the script again and got a core dump.

So the last one is probably a problem to look at. But are these files
supposed to be compatible across os's?

Is it that solaris is using dbm and linux is using gdbm or some other
combination?

I can provide files if needed.
