        <div>
        <pre>Upon attempt to compile this code:

#include <stdio.h>
#include <unistd.h>

void
foo(int i)
{
  if (i < 0)
     goto whoops;

  if (i == 0)
     printf("foo\n");

  if (i > 0)
     goto corrupt;
  return;

whoops:
  printf("whoops\n");
  return

corrupt:
  printf("corrupt\n");
}

Clang prints the following:

foo.c:21:1: error: use of undeclared identifier 'corrupt'; did you mean
'crypt'?
corrupt:
^~~~~~~
crypt
/usr/include/unistd.h:542:7: note: 'crypt' declared here
char    *crypt(const char *, const char *);
         ^
foo.c:21:8: error: expected ';' after return statement
corrupt:
       ^
       ;
foo.c:14:11: error: use of undeclared label 'corrupt'
     goto corrupt;
          ^
3 errors generated.

Which is not correct, since 'corrupt' is correct label, even though it's
defined after incorrect line ('return' statement doesn't terminate with ';')</pre>
