In reply to comment #14:

No, it's aimed at the problem from the description. That is, GCC itself doesn't
work if compiled with a compiler where f(int a, int b) is called differently
than f(int a, ...). I don't think your testcase is actually supposed to work.
Don't you get a warning if you take out (void *) and compile with -Wall?
As pinpointed in comment #2, GCC contains the same incorrect type cast. I
actually forgot to patch this part:
