It actually seems that the cast (long)__null is performed somewhere (where?) while parsing, while (int)__null is just accepted as __null. I tried to follow up the code with just long i = (long) __null; but the C++ front-end is impossible to debug for me. It just jumps again and again to the same places. Is there any trick to debug this kind of thing? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=5310
