The same comma typo bug could happen in C.

  execl("/bin/sh", "/bin/sh", "-c"
        "echo foo", (char *) NULL);

Here we get one "-cecho foo" argument passed to the shell instead of two, so it can't work.

Initializers are another example:

  char *strArray[] = {
    "how", "now"
    "brown", "cow"
  };

In non-variadic function and macro calls, you will most likely get an insufficient arguments error, unless another mistake compensates for that.
