Question

Is there a way in log4Perl that I can force my programs to log fatal even outside an eval clause? I want to achieve to call log4perl also in case of any unhandled program termination. Prefereably I would like to add the related error handler inside my standard module which is loaded with all my Perl programs.
The Perl version is currently 5.8, but I am upgrading soon.
This the test code for the given answer. I see neither a DIE on the screen nor that die.txt is created.

 use Log::Log4perl qw(get_logger);
$a->test();
$SIG{__DIE__} = sub {
 warn "DIE";
 open DIE,">die.txt";
 print DIE "died\n";
 close DIE;
};

Looks like the FAQ How can I make sure my application logs a message when it dies unexpectedly?

use Log::Log4perl qw(get_logger);

$SIG{__DIE__} = sub {
    if($^S) {
        # We're in an eval {} and don't want log
        # this message but catch it later
        return;
    }
    local $Log::Log4perl::caller_depth =
          $Log::Log4perl::caller_depth + 1;
    my $logger = get_logger("");
    $logger->fatal(@_);
    die @_; # Now terminate really
};
