开启xhprof会Segmentation fault

[chefxu]

我不确认属于xhprof的问题还是yaf的问题， 试了主干的代码和最新tag版本的代码， 都有这个问题。

堆栈信息如下：

重现代码如下：

function main() {
echo "hello,world\n";
xhprof_enable(XHPROF_FLAGS_CPU + XHPROF_FLAGS_MEMORY);
}
$application = new Yaf_Application($config);
$application->execute('main');

这个不是Yaf的问题, 是xhprof的问题, 我曾经给他们提交过这个问题的patch, 应该他们最新版已经修复了吧.

xhprof主干上的代码还是有问题， 不过用了patch后ok了， 多谢帮助！

最新版依然有问题，下鸟哥的分支可以正常运行。
