cc2541 IAR 编译报错 Range error

我用的是stack是1.4.2.2  , IAR 9.10.3,  例改自simpleBLEPeripheral例程， MAP文件内容是这样的：

Error[e18]: Range error,

Number out of range

File: C:\Texas Instruments\BLE-CC254x-1.4.2.2\Projects\ble\SolarStreetlight\Source\simpleBLEPeripheral.c, Line: 1857

真的好奇怪，已经排除了空间不足问题，出现得比较随机，偶尔出现，举个例子，只是一种情况，如下
if(condition)
{
//do something
}
else
{
// do something
}
这时编译不通过！
当我改成
if(condition)
{
//do something
}
//else //注释了else
{
// do something
}
就通过了

还有一种解决办法，当出现不通过时，只要我在程序中特定位置加入nop就能能解决，如改成如下
if(condition)
{
//do something
asm("nop");
}
else 
{
// do something
}
它又能链接成功了！

这是我之前贴，找了很久没找到原因，麻烦帮忙看看，e2echina.ti.com/.../165033

这次我精简了代码，定位到一个函数里，这个函数精简过没有什么意义，但能重现问题。源代码见附件。

感觉各IAR的高优化有关。。

请看代码

//#pragma optimize = none  单独不开优化也可以

我以前公司电脑中安装的有加密软件，经常会导致这样的问题，不知道你的电脑可有类似的加密软件
