Not sure if it's the same bug, but 3.4 outputs
nothing for this code with -O2:

  static int foo __attribute__((unused)) = 42;

This breaks the Linux kernel (the __setup() macro).
GCC 3.3.1 did the right thing:

        .data
        .align 4
        .type   foo, @object
        .size   foo, 4
foo:
        .long   42
