struct atomic {
unsigned long my_value;
public:
atomic() = default ;
atomic(unsigned long value) : my_value(value) {}
unsigned long load() {
int32_t* v = reinterpret_cast<int32_t*>(&my_value);
return (volatile int32_t&)(*v);
}
you are initializing my_value as long but read from it as int32_t, that
violates strict-aliasing rules.
