Perl进程陷入«；***glibc检测到***perl:损坏的双链接列表：0x0000000001474b40***»；-我怎样才能让它终止？

我一直在尝试用Perl 5和XML:：LibXML（我现在维护）调试内存损坏问题。现在我得到的是：

shlomif@lap:~/progs/perl/cpan/XML/LibXML/bugs/perl-xml-libxml-bugs/XML-LibXML-reader-segfault$ make test
XML_CATALOG_FILES="`pwd`/sgml-lib/catalog.xml" perl find_ascii_quotes.pl index.html
*** glibc detected *** perl: corrupted double-linked list: 0x0000000001474b40 ***
^Cmake: *** [test] Interrupt

然后，Perl进程被卡住，无法返回shell。问题是，Perl进程停止的事实中断了我的流程，我正在寻找一种方法，让进程崩溃或其他什么，而不是挂在那里。GDB报告如下。您可以在中找到有问题的代码（只需运行“make test”），我正在x86-64上进行Mandriva Linux开发（Cooker）
