用的是macOS系统安装的clion
在执行如下代码时出错.

error: <user expression 1>:1:2: use of undeclared identifier 'value'
&value
 ^
报错代码如上方所示

断点执行时可以看出来kRed已经为0了.

&value = error: <user expression 7>:1:2: use of undeclared identifier 'value'
&value
 ^

kRed = {const int} 0
kGreen = {const int} 65280
kBlue = {const int} 255
p_k_red = {int * | 0x7ffeec0b1a88} 0x00007ffeec0b1a88

最后输出结果却没有变化.
