<pre>
    The code is as follows:

`int cpu_ (void *attr) {}
const unsigned long _1 __attribute__((section("__"))) = (unsigned long)&cpu_ ;
const unsigned long _group __attribute__((section("__"))) = 0;`

GCC accepts the code, but clang rejects it:

ode0.c.cpp:1:24: warning: non-void function does not return a value [-Wreturn-type]
    int cpu_ (void *attr) {}
 ^

GCC <4.6 also rejects this code. It is fixed in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=31490
