That's not a value-dependent error.  1 / 0 has a sensible type (it's
an int), but no sensible value; 1 >> 3.0 has no sensible type (it's a
syntax error).

I think of it this way:

drow@caradoc:~% cat a.c
int a = sizeof (1/0);
int b = sizeof (1 >> 3.0);
drow@caradoc:~% gcc -Wall -c a.c
a.c:2: error: invalid operands to binary >>
