package XX;

use nginx;

sub handler {
        my $request = shift;

        if ( $request->request_method eq 'GET' ) {
                $request->send_http_header( 'text/html' );
                $request->print("GET");
        }
        elsif ( $request->request_method eq 'POST' ) {
                $request->send_http_header( 'text/html' );
                $request->has_request_body( \&XX::GetPostParams );
                $request->print("POST");
        }
        else {
                return DECLINED;
        }

        return HTTP_OK;
}

sub GetPostParams {
        my $r = shift;

        return OK;
}

42;

с GET вс нормально, но если послать POST запрос, функция GetPostParams
выполняется, а потом воркер сегфолтится. видел, что похожая ошибка
была пофикшена в 0.6.22, но потом либо снова  появилась, либо это
что-то другое.
пробовал на nginx-0.6.31, 0.6.32 и 0.7.13

ось: CentOS 5.1

на 0.7.13 в логе перед сегфолтом вылазит вот такое:
