This is ..

cc (GCC) 4.2.1 20070831 patched [FreeBSD]

 .. on ..

FreeBSD 11.0-CURRENT #22 r263969: Mon Mar 31 10:45:56 EDT 2014

Splitting it like ..

-       fn.fn_ptr.cxa_func = (void(*)(void*))GET_BLOCK_FUNCTION(func);
+       fn.fn_ptr.cxa_func =
+               (void(*)(void*))
+               GET_BLOCK_FUNCTION(func);

 .. causes the reported error to point at the GET_BLOCK_FUNCTION.

I guess it's time for me to migrate that box to clang :-)
