[Bioperl-l] Bio::Tools::SimpleAnalysisBase triggers Data::Dumper core dump on FreeBSD 4

[Peter van Heusden]

The run() method in Bio::Tools::SimpleAnalysisBase triggers a core dump 
in perl 5.8.5 on FreeBSD 4-STABLE. The core dump is coming from the 
usage of Data::Dumper's Dump method. Here's what run() looks like:

sub run {
    my ($self, $args) = @_;
    $self->_process_arguments ($args) if $args;
                                              
    # check input                             
    $self->throw("Need a sequence object as an input") unless $self->seq;
    $self->debug(Data::Dumper->Dump([$self],[$self]));                  
                                                     
    # internal run()                                 
    $self->_run;   
    return $self;
}

The ->debug line is where the core dump happens, in the Dump() method. 
I'm investigating further, since this presumably isn't Bioperl's fault, 
but thought I should should just report this for now. I found this while 
testing the t/Sopma.t test with BIOPERLDEBUG on.

P.S. the coredump goes away when I set Data::Dumper::Useperl to 1.
