[ID 19991102.004] closing STDERR confuses perl's warn & die
Message ID:

This is a bug report for perl from Raphael_Manfredi@pobox.com,
generated with the help of perlbug 1.26 running under perl 5.00503.


-----------------------------------------------------------------
The following script:

     1  open(STDERR, '>std.err');
     2  warn "test #1";
     3  close STDERR;
     4  open(STDERR, '>std2.err');
     5  warn "test #2";
     6  die "fatal";
     7  close STDERR;

when ran produces two files:

    -rw-r--r--   1 ram      users          23 Nov  2 23:30 std.err
    -rw-r--r--   1 ram      users           0 Nov  2 23:30 std2.err

The first contains

     1  test #1 at bug line 2.

as expected. The second one is empty!

I'm running Debian 2.1 with some 2.2 packages unfortunately.
My kernel is Linux 2.0.38.
