Problem using aspell 0.6 via Text::Aspell

Hi,

When I get the suggestion of "__"(or more "_") using Text::Aspell by the 
following lines:

$speller->set_option('lang', "it");
$word = "__";
$speller->suggest($word);

It crashed!

The problem also exist when using ru as the language.

I can't confirm what signal it generated to make my program exit.

Please help!

Many thanks.
