Using clang r47211, and llvm r47211 I cannot compile the code below.
gcc and icc compile the code without errors.

$ clang -fsyntax-only testcase-min.i
testcase-min.i:10:9: error: initializer element is not constant
        {"OPEN", 1, &cdiff_cmd_open }
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 diagnostic generated.

$ gcc -Wall -c testcase-min.i
testcase-min.i:9: warning: ‘commands’ defined but not used
$ icc -w2 -c testcase-min.i
testcase-min.i(9): remark #177: variable "commands" was declared but never
referenced
  static struct cdiff_cmd commands[] = {
                          ^

$ cat testcase-min.i
struct cdiff_cmd {
          const char *name;
          unsigned short argc;
          int (*handler)();
};
static int cdiff_cmd_open() {
  return 0;
}
static struct cdiff_cmd commands[] = {
        {"OPEN", 1, &cdiff_cmd_open }
};
