昏晕几天！！！while(1)线程被莫名杀死！或阻塞！求救。。。
( 俺不知道while(1)函数的实例是否叫线程，若有错，请指正)

main()
{
   ......
   ......
   while(1){
// 如果没有输入就继续循环
// 若有输入就执行以下程序
  ......
   ......
  }
}

/* 中断处理函数，没各1秒钟，内核唤醒执行，可以中断while(1)循环 */
void inthandler()
{ printf("......");
   // 画一个圆圈
  .......
}

请问！！！中断处理函数有可能杀死while(1)或阻塞它么？？？
若有，那是什么样的情况？

呜呜。。。我想晕了。。。不得其解！

现实情况：
    程序执行后，while(1)转了几圈之后就停止了，只有中断程序还按时中断执行。。。。

提醒：并不是任何函数都可以在 sig_handler 中调用，其中也包括 printf
建议：google 一下 "异步信号安全函数"

贴一堆输出结果，也不贴代码？ft

同意，可能是不能安全“重入”的问题。

问题已想明白了！！！（灵感作用）
先说一下：不好意思，我是“交叉编译”，不是在PC上运行的代码，源代码有些混乱，数百行，很多都与我所遇到的问题无关，与讨论有关的代码有很难抽取，我是怕麻烦。。。

问题所在：（很可能，也许就是这样！！！）

ARM920处理器的能力有限，当发生几次后，中断程序要处理的问题增多了一两句，也许就因为增多了那几句（包含数需函数），结果就在那时发生了中断，中断被阻塞，结果就是，中断执行完毕后又是中断，中断无法返回！！！！

非常感谢 anO 前辈的指点！

痛苦啊，想了3天，大脑差点承受不住！（我最怕不明不白。。。）

忘记了，同时也感谢anthonylee 兄的指点

因为指点，所以感悟，呵呵
