Hello,

I am receiving the gcc compiler warning -Wunused-value computed not used. I
can confirm this is true in my embedded application, the statement never
switches. But I am completely confused as to why. It's essentially the
following code:

volatile bool foo;

while (true) {
if (foo == true){
       //do something
       foo = false;}
else{
       //do something else
       foo = true;}
}

Which never switches. What could be the cause of this?

Many thanks in advance!
