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.
