Uhm. No. Certain compilers will give you warnings for f(g(a), g(b))
if you -Wall.
Warn on what exactly ?
That f's arguments are evaluated in an unspecified order.
Which compilers do that ?
For all you know, gcc 4.7.
New gcc releases regularly issue lots of new warnings for correct code,
particularly with -Wall. Other compilers are even worse.
Did it actually occur to anyone that warnings are not errors? You can
have them for correct code. A warning means you might want to look at
the code to check whether there's some real error there. It doesn't
mean the code is broken.
