No. It's due to integer promotion. All operations are done at the int  
level, so the expression b + c is actually an int. C allows this  
transgression because it's convenient. D makes you acknowledge that you  
are throwing away bits the compiler generated for you.

Note, += does work:

a = b;
a += c;
