oops... I was trying to simplify the example that I posted, so I removed
that printf from the example code, but I forgot to remove it from the
output. Here's the actual code:
#include <stdio.h>
class MyClass {
public:
short int foo_ : 6;
};
int main(int argc, char *argv[]) {
MyClass *gce = new MyClass();
double d=0.0;
if (d == 0.0) {
printf("d equals zero.\n");
printf("myclass size is %d\n", sizeof(MyClass));
}
return 0;
}
