When compiling the following file with g++ 4.3.0, with -Wall :
---- main.cpp ----
struct foo {
bool a;
volatile bool b,c; // removing 'volatile' here removes the warning.
foo() { a = b = c = false; }
};
int main() {
foo A;
}
-- end of main.cpp --
-bash-3.00$ g++ main.cpp -Wall
tata.cpp: In constructor 'foo::foo()':
tata.cpp:4: warning: suggest parentheses around assignment used as truth value
It seems that having an assignement between 'volatile' and non-volatile bools
activates the warning. I don't see any reason why it should behave like this.
Removing the volatile keyword (or adding it in the line above) removes the
warning.
