我正在尝试使用--command标志自动化gdb会话.我正在尝试在共享库(Unix的等价物DLL)中的函数上设置断点.我的cmds.gdb看起来像这样:
set args /home/shlomi/conf/bugs/kde/font-break.txt
b IA__FcFontMatch
r
但是,我得到以下内容:
shlomi:~/progs/bugs-external/kde/font-breaking$ gdb --command=cmds.gdb... GNU gdb 6.8-2mdv2009.0 (Mandriva Linux release 2009.0) Copyright (C) 2008 Free Software Foundation, Inc.

我一直在尝试使用Perl 5和XML :: LibXML(我现在维护)调试内存损坏问题.现在这就是我得到的:
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进程卡住了,不会返回shell.事实上,Perl进程停止的事实会中断我的流程,而我正在寻找一种方法让进程崩溃或者不管是什么而不是挂在那里.GDB报告下面的内容.可以在Mercurial存储库中找到有问题的代码(只需运行"make test"),然后我就在x86-64上进行Mandriva Linux开发(Cooker).
ader-segfault$ gdb --command=cmds.gdb /usr/bin/perl

# We reserve a random port to make sure the localhost address is not
# valid. See:
#
# https://rt.cpan.org/Ticket/Display.html?id=52422
my $sock = IO::Socket::INET->new(
Proto => 'tcp',
);
my $port = $sock->sockport();
$file = "http://localhost:${port}/allow.xml";
现在,问题是在Linux上定义了$ port并且有效(对于保留端口的值),但它似乎无法在Windows上运行 - 请参阅此错误报告 - https://rt.cpan.org/Ticket /Display.html?id=71456.我的问题是:如何在Perl 5中的UNIX,Mac OS X和Windows上预留一个新的,随机的,尚未占用的端口？

在Toggle Squares页面中,我在JavaScript生成的每个单元格中都有一个由<img />组成的表.我应用了以下CSS:
.game, .game td, .game tr, .game img
{
border: none;
border-spacing: 0;
padding: 0;
margin: 0;
}
为了消除所有间距.但是,现在我在两个相邻行之间得到一条很细的背景线.我怎样才能消除它？
该页面是有效的XHTML + CSS.
谢谢你的帮助.
问候,
