GOTCHA! Try these two

int function_with_some_side_effects();

other func()
{
	int a,b;

	b = function_with_side_effects(some_global);
	a = b + function_with_side_effects(some_global);
}

---OR---
{
	int a,b;
	b = function_with_side_effects(some_global);
	a = b ; function_with_side_effects(some_global);
}
	      ^
	      +-- Grade A typo, if you keyboard has '+' as SHIFT ';'
		  (such as this keyboard, a TVI955)

Enough said.. .
