Why do you think that?

It does generate a call to func but not as you expected it.

Anyways the way GCC is compiling your code is the following which is valid
under the standard:

int *a, *b, *c;
c = func(3);
b = func(2);
a = func(1);

  printf("%d %d %d\n", *(a), *(b), *(c));

so the order is still undefined as there is no sequence point between the
function calls.
