奇怪的Floating Point Division By Zero问题.....

yang_jnu 2011-09-28 10:24:45

按照错误提示，问题应该出在除以0，但我根本就没有除法运算，于是单步调试，发现错误出在一个ShowMessage语句，函数简略如下：
void function(void) {
... // 位置1
for (int i = 0; i < 6; i ++) {
... // 位置2
pWirelessCfg->mod_en[i] = 0xAA // 其中pWirelessCfg为指向一个结构体的指针，成员mod_en为unsigned char
// 类型的数组
ShowMessage("Error take place!"); // 运行此语句，提示除以0错误
...
}
... // 位置3
}
程序运行到ShowMessage语句时会弹出一个Floating Point Division By Zero的错误，点确定后程序照常运行，如果省略ShowMessage语句，程序正常运行。

我作了几种测试：
1. 将0xAA改为其它值，运行不会出现错误，例如0xBB等，仅为0xAA才出错
2. 将ShowMessage语句放在pWirelessCfg->mod_en[i] = 0xAA语句前的任何一个位置，如位置1，2，ShowMessage语句都不会出错
3. 将ShowMessage语句放在pWirelessCfg->mod_en[i] = 0xAA语句后的任何一个位置，如位置3，ShowMessage语句就会出现Floating Point Division By Zero错误提示
4. 用MessageBox替换ShowMessage后同样出现这种问题（感觉好像只要放在pWirelessCfg->mod_en[i] = 0xAA语句后面的弹窗操作都会出现这种错误）

上面都是简单的调试，但让我疑惑了好久。。。希望得到高手指点！！！

光这段程序看不出什么问题.可能的问题是因为数组越界导至程序数据区崩溃.特别是程序复杂时,这种情况很常见

首先感谢你的回答，一开始我也认为是可能是数组越界之累的，将0xAA改为其它值，运行就不会出现错误了，纳闷中....此外，今天调试时发现：之前，function函数的调用放在FormCreat里面调用时会出错的，在我的主窗口完成后再调用function就不会有问题，感觉就像只要在pWirelessCfg->mod_en[i] = 0xAA这句话前面出现了窗口，比如说用showMessage()弹出的窗口或者是主窗口，程序就不会出现Floating Point Division By Zero的问题

mod_en[i]可能超过数组范围了. 还是检查是否越界吧
