Re: confusing messages from clang

[Alex Denisov]

Hi Steve,

I’ve submitted the bug to LLVM’s bugzilla: 
https://llvm.org/bugs/show_bug.cgi?id=26678

Also, it looks like OS agnostic. At least I see the same behaviour on OSX as 
well.

confusing messages from clang

[Steve Kargl]

If anyone is interesting fixing FreeBSD's C compiler, it
would be appreciated.

% cat foo.c
#include 
#include 

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");
}

% cc -c foo.c
foo.c:21:1: error: use of undeclared identifier 'corrupt'; did you mean 'crypt'?
corrupt:
^~~
crypt
/usr/include/unistd.h:450:7: note: 'crypt' declared here
char*crypt(const char *, const char *);
 ^
foo.c:21:8: error: expected ';' after return statement
corrupt:
   ^
   ;
foo.c:14:12: error: use of undeclared label 'corrupt'
  goto corrupt;
   ^
3 errors generated.


No, I did not mean crypt.  'corrupt' is a defined label.
The missing semicolon occurs in line 19, but the line is
not properly identified in error output.
